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 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 hands for:

Inspect the head for:

Then inspect the precordium for:

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:

Palpation of the precordium

The valve areas are palpated for abnormal pulsations (palpable heart murmurs known as thrills) and precordial movements (known as heaves). Heaves are best felt with the heel of the hand at the sternal border.

Palpation of the apex beat

The apex beat is found approximately in the 5th 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 ankles are checked for pitting edema which is caused by right ventricular failure in isolation or as part of congestive cardiac failure.

Auscultation

One should comment on

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.
