WebbThe electrocardiogram can measure the rate and rhythm of the heartbeat, as well as provide indirect evidence of blood flow to the heart muscle. A standardized system has been developed for the electrode placement for a routine ECG. Ten electrodes are needed to produce 12 electrical views of the heart. Webb1. Tall 'tented' T waves. In the presence of hyperkalemia, the T wave on the ECG/EKG rises in amplitude (A, below). In text books, we are told that in a given lead, the T wave should be no more than half the amplitude of the preceding R wave. In reality, ‘tall’ T waves are quite common on the ECG of normal individuals, particularly young ...
