体检结果上写 ECG:Q 是什么意思

admin

ECG可以理解为electonic(电) cardiac(心脏的)gram(图) 俗称心电图 。 分为 P, QRS, T wave. P 是由心房的去极化引起 。 Q 是由于心室去极化之前,细胞做准备时形成的。

不好意思,我学的是英文的,不知道解释清楚没。

P walve is because of the atrial depolarization.

QRS, we always put the three walve together ,cause they are all caused by ventricle activation.

Q is because the initial deflection from ventricular depolarization( interventriclar septal deporization)

R walve: first positive deflection from ventricular depolarization.

S walve:first negative deflection following R wave.

T wave: ventriculat repolarization
