Indications and clinical importance of E.C.G

The electrocardiogram (ECG) is the graphical representation of various changes of electrical potential in the heart (cardiac muscle fibre) during a cardiac cycle which can be recorded by placing suitable electrode over the body surface known as the electrocardiogram (ECG).

Indications of E.C.G.:

Physiological

  • Normal heart rate is counted
  • Characteristics of heartbeat can be determined
  • Condition heart can be detected.

Clinical

From ECG, following conditions should be detected –

(i) Atrial & ventricular hypertrophy.

(ii) Myocardial infarction is chemia.

(iii) Pericarditis.

(iv) Heart block.

(v) Systemic diseases that affect the heart.

(vi) Any valvular abnormalities like arrhythmia, fibrillation, flutter, abnormal pulse etc.

(vii) Effects of drugs like – (a) Digitalis, (b) Quinine.

(viii) Hyperkalemia.

Clinical Importance of ECG-

The Clinical Importance of E.C.G. is obviously very great. It gives the accurate condition of atria and ventricle almost in all of its functional aspects. After all, it is the dependable side to diagnosis, prognosis, and treatment. It is an important tool used for the diagnosis and treatment of various cardiac and other related diseases. The recorded tracing of the ECG waveforms produced by the heart can tell you basic information about a patient’s condition.
