A

Tachycardia

87
Q

In ____ syndrome an abnormal bridge of tissue connects the atria to the ventricles. This allows the cardiac impulse to bypass the AV node resulting in a very rapid heartbeat.

This is a rapid, regular heartbeat originating in the ventricles, generating a pulse of 100-250 bpm. Usually a medical emergency.

A

Ventricular tachycardia

89
