You do not have permission to edit this page, for the following reasons:

This IP address has been blocked from editing Wikipedia.
This does not affect your ability to read Wikipedia pages.
Most people who see this message have done nothing wrong. Some kinds of blocks restrict editing from specific service providers or telecom companies in response to recent abuse or vandalism, and can sometimes affect other users who are unrelated to that abuse. Review the information below for assistance if you do not believe that you have done anything wrong.

The IP address or range 44.201.0.0/16 has been blocked (disabled) by ‪ST47‬ for the following reason(s):

The IP address that you are currently using has been blocked because it is believed to be a web host provider. To prevent abuse, web hosts may be blocked from editing Wikipedia.
You will not be able to edit Wikipedia using a web host provider because it hides your IP address, much like a proxy or VPN.
We recommend that you attempt to use another connection to edit. For example, if you use a proxy or VPN to connect to the internet, turn it off when editing Wikipedia. If you edit using a mobile connection, try using a Wi-Fi connection, and vice versa. If you are using a corporate internet connection, switch to a different Wi-Fi network. If you have a Wikipedia account, please log in.
If you do not have any other way to edit Wikipedia, you will need to request an IP block exemption.

How to appeal if you are confident that your connection does not use a web host's IP address:
If you are confident that you are not using a web host, you may appeal this block by adding the following text on your talk page: ((unblock|reason=Caught by a web host block but this host or IP is not a web host. My IP address is _______. Place any further information here. ~~~~)). You must fill in the blank with your IP address for this block to be investigated. Your IP address can be determined here. Alternatively, if you wish to keep your IP address private you can use the unblock ticket request system. There are several reasons you might be editing using the IP address of a web host (such as if you are using VPN software or a business network); please use this method of appeal only if you think your IP address is in fact not a web host.

Administrators: The IP block exemption user right should only be applied to allow users to edit using web host in exceptional circumstances, and they should usually be directed to the functionaries team via email. If you intend to give the IPBE user right, a CheckUser needs to take a look at the account. This can be requested most easily at SPI Quick Checkuser Requests. Unblocking an IP or IP range with this template is highly discouraged without at least contacting the blocking administrator.

This block will expire on 23:54, 31 July 2024.

Even when blocked, you will usually still be able to edit your user talk page, as well as email administrators and other editors.

For information on how to proceed, please read the FAQ for blocked users and the guideline on block appeals. The guide to appealing blocks may also be helpful.

In [[medicine]], the '''cardiac examination''', also '''precordial exam''', is performed as part of a [[physical examination]], or when a patient presents with [[chest pain]] suggestive of a cardiovascular [[pathology]]. It would typically be modified depending on the [[Indication (medicine)|indication]] and integrated with other examinations especially the [[respiratory examination]].

Like all medical examinations, the cardiac examination follows the standard structure of inspection, palpation and auscultation.

==Positioning==
The patient is positioned in the [[supine position]] tilted up at 45 degrees if the patient can tolerate this. The head should rest on a pillow and the arms by their sides. The level of the jugular venous pressure (JVP) should only be commented on in this position as flatter or steeper angles lead to artificially elevated or reduced level respectively. Also, left ventricular failure leads to [[pulmonary edema]] which increases and may impede breathing if the patient is laid flat.

Lighting should be adjusted so that it is not obscured by the examiner who will approach from the right hand side of the patient as is medical custom.

The torso and neck should be fully exposed and access should be available to the legs.

==Inspection==
General Inspection:
* Inspect the patient status whether he or she is comfortable at rest or obviously short of breath.<ref>250 cases in clinical medicine 3rd edition. R. R. Baliga</ref>
* Inspect the neck for increased jugular venous pressure (JVP) or abnormal waves.<ref>250 cases in clinical medicine 3rd edition. R. R. Baliga</ref>
* Any abnormal movements such as head bobbing.
* There are specific signs associated with cardiac illness and abnormality however, during inspection any noticed [[List of cutaneous conditions|cutaneous sign]] should be noted.

Inspect the hands for:
* Temperature – described as warm or cool, clammy or dry
* Skin turgor for hydration
* [[Janeway lesion]]
* [[Osler's node]]
* At the nails [[Splinter hemorrhage]] and Quincke's pulsation should be looked for as well as any deformity of the nail such as [[Beau's lines]], [[Nail clubbing|clubbing]] or [[Cyanosis#Peripheral cyanosis|peripheral cyanosis]].

Inspect the head for:
* Cheeks for the malar flush of [[mitral stenosis]].
* The eyes for [[corneal arcus]] and surrounding tissue for [[xanthalasma]].
* Conjunctiva pallor a sign of anemia.
* The mouth for hygiene.
* The mucosa for hydration and pallor or central [[cyanosis]].
* The ear lobes for [[Frank's sign]].

Then inspect the precordium for:
* visible pulsations
* [[apex beat]]
* masses
* scars
* lesions
* signs of trauma and previous surgery (e.g. [[median sternotomy]])
* any signs of previously-implanted cardiac hardware such as pacemakers or implated cardiac defibrillators
* precordial bulge

==Palpation==
The pulses should be palpated, first the [[radial pulse]] commenting on rate and rhythm then the brachial pulse commenting on character and finally the [[carotid pulse]] again for character.
The pulses may be:
* [[Watson's water hammer pulse|Bounding]] as in large pulse pressure found in [[aortic regurgitation]] or [[Hypercapnia|((CO2)) retention]].
* And the rhythm should be assessed as regular, regularly irregular or irregularly irregular.
* Consistency of the strength to assess for [[Pulsus alternans]].
* Slow rising as found in [[aortic stenosis]] known as parvus et tardus
* Jerky as found in [[HOCM]]
* Pulses can also be auscultated for features like [[Aortic insufficiency#Physical examination|Traube's pistol shot femoral pulse]].

===Palpation of the precordium===
The valve areas are palpated for abnormal pulsations (palpable [[heart murmur]]s known as ''thrills'') and precordial movements (known as ''[[Parasternal heave|heaves]]'').  Heaves are best felt with the heel of the hand at the [[Human sternum|sternal]] border.

===Palpation of the apex beat===
The [[apex beat]] is found approximately in the fifth left [[intercostal space]] in the [[mid-clavicular line]]. It can be impalpable for a variety of reasons including [[obesity]], [[emphysema]], [[effusion]] and rarely [[dextrocardia]]. The apex beat is assessed for size, amplitude, location, impulse and duration. There are specific terms to describe the sensation such as tapping, heaving and thrusting.

Often the apex beat is felt diffusely over a large area, in this case the most inferior and lateral position it can be felt in should be described as well as the location of the largest amplitude.

Finally the [[sacrum]] and [[ankle]]s are checked for [[pitting edema]] which is caused by [[Heart failure#Right-sided failure|right ventricular failure]] in isolation or as part of [[congestive cardiac failure]].

==Auscultation==
One should comment on
* S1 and S2 – if the splitting is abnormal or louder than usual.
* S3 – the emphasis and timing of the [[syllables]] in the word ''Kentucky'' is similar to the pattern of sounds in a precordial S3.
* S4 – the emphasis and timing of the [[syllables]] in the word ''Tennessee'' is similar to the pattern of sounds in a precordial S4.
* If S4 S1 S2 S3 Also known as a [[gallop rhythm]].
* diastolic murmurs (e.g. [[aortic regurgitation]], [[mitral stenosis]])
* systolic murmurs (e.g. [[aortic stenosis]], [[mitral regurgitation]])
* [[pericardial rub]] (suggestive of [[pericarditis]])
* The base of the lungs should be auscultated for signs of pulmonary oedema due to a cardiac cause such as bilateral basal [[Crackles|crepitations]].

==Completion of examination==
To complete the exam blood pressure should be checked, an [[ECG]] recorded, [[funduscopy]] performed to assess for [[Roth spots]] or [[papilledema]]. A full peripheral circulation exam should be performed.
