ABSTRACT
Most ECG machines automatically include a rhythm strip at the bottom of a 12-lead electrocardiogram (ECG). A similar approach to the ECG is used by the Resuscitation Council (UK) to train healthcare professionals in rhythm recognition. The standard lead used for the rhythm strip is lead II, but alternative leads can be selected if it helps to clarify the cardiac rhythm. The diagnosis of abnormal cardiac rhythms is not always easy, and some of the more complex arrhythmias can tax the skills of even the most experienced cardiologist. Ventricular rhythms are generated within the ventricular myocardium; supraventricular rhythms are generated anywhere up to the AV junction. Each rhythm has its own set of ECG characteristics, and by assessing the ECG in a methodical manner one will quickly learn how to distinguish between them.
