SpletA PAC can conduct normally, demonstrating the same QRS morphology as in sinus rhythm, though P wave and PR interval may be different than for a normal sinus beat. If the PAC occurs at a short interval after a normal beat (short coupling interval ), a portion of the conduction system may be in its refractory period from the prior activating beat. SpletA short PR interval may be associated with an otherwise normal electrocardiogram or a myriad of bizarre electrocardiographic abnormalities. Clinically, the individual may be asymptomatic or experience a variety of complex arrhythmias, which may be disabling and rarely cause sudden death.
