The essential components of an ECG #IndiaNEWS #Education Today
Hyderabad: This article is in continuation of the previous articles that help you understand what constitutes the biological sciences and its varied branches/ concepts. Today, we would be discussing the fourth part of the Biomedical technology with a focus on Electrocardiogram (ECG).
A normal ECG consists of
i. Waves
ii. Intervals
iii. Segments
iv. Complexes
Waves:
* The waves in a normal record are named P,Q,R,S & T in that order
* A typical ECG tracing of a normal heart beat (or cardiac cycle) consists of
a. ‘P’ wave
b. ‘QRS Complex’ of waves
c. ‘T’ wave
‘P’ Wave:
* It represents the atrial depolarisation/atrial systole.
* ‘P’ wave shows that the impulse is passing through the atria.
* The normal duration of a ‘P’ wave is – 0. 1 sec
‘QRS Complex’ of waves:
* ‘Q’ wave is a small negative wave.
* ‘R’ wave is a tall positive wave.
