An electrocardiogram is a machine used to record the heart's electrical activity. A fast heartbeat is called tachycardia, while a slow heartbeat is called bradycardia in medical terms. Cardiac arrest Cardiac arrest is a medical emergency in which the heart stops pumping blood to the body.

The rule of thumb is less accurate, and the risk is higher because a long QT in the presence of bradycardia ("pause dependent" Torsades) predisposes to Torsades. 6) Use a different rule of thumb for bradycardia : Manually approximate both the QT and the RR interval. 3) At heart rates below 60, far more caution is due.

Further history later: This patient personally has no further high risk features (syncope / presyncope), but her mother had sudden cardiac arrest in sleep. Regardless of further evaluation, she should avoid bradycardia, AV nodal blockers, Na channel blockers, and fevers. --If

Theres sinus bradycardia, borderline PR interval, narrow QRS; normal axis/R wave progression; low precordial voltages, and subtle peaked T waves (most obvious in V2, but all T waves are symmetric with a narrow base). Theres no prior ECG to compare - but the bradycardia, prolonged PR and peaked T waves could all be from hyperkalemia.
