ECG Introduction to ECG interpretation The normal T wave Assessment of the T wave represents a difficult but fundamental part of ECG interpretation. The normal…

…length of the refractory period (see Basic Cardiac Electrophysiology) varies with heart rate. The length is shortened as heart rate increases and vice versa. Thus…

…As the heart rate increases, the QT interval decreases and vice versa. The physiological purpose of this phenomenon is to allow for faster cardiac cycles…

…Cardiac cells are highly capable of matching the supply and demand of ATP; increased cardiac workload results in increased ATP production and vice versa. Importantly…
