Understand the terms: At 23, possibility of cardiac arrest is remote even with family history. SINUS TACHYCARDIA is a rapid, otherwise normal beat. SINUS ARRYTHMIA refers to the normal variation in pulse rate with the breathing cycle seen in young athletes. PVCs are extra beats generated in lower chamber for many reasons, rarely serious. PALPITATIONs are literally the awareness of your heartbeat caused by any of these.
