Sinus Arrest/Pause heart rhythm originating in the sinoatrial node with a rate in patients at rest of 60 to 100 beats per minute Appearance is ALMOST NORMAL: Respiratory - Circulatory interaction Rate INCREASES with INSPIRATION (IN=IN) <60 normal sinus rhythm >100 (100-150) normal sinus rhythm Heart Rate: Depends on underlying rhythm Regularity: Interrupts the regularity of underlying rhythm P-Wave: can be flattened, notched, or unusual. May be hidden within the T wave PRI: measures between .12-.20 seconds and can be prolonged; can be different from other complexes QRS: <.12 seconds - SA node doesn't fire - notice absence of P-wave for a complete cycle (a missed cycle) length of pause ` multiple of normal rate (block) 2 / 5 BASIC DYSRHYTHMIA-R
