· PACs momentarily interrupt the normal sinus rhythm by inserting an extra heartbeat Because a PAC can reset the sinus node, there is usually a short pause before the next normal heartbeat occurs As such, PACs are often perceived as a skip in the heartbeatWith normal sinus rhythms, the heart beat's electrical impulse originates in the sinoatrial node (SA) The P waves are upright and appear before each QRS and have the same shape The intervals between the P waves are regular although some variations can occur with respiration Sinus rhythms are classified as Normal Sinus Rhythm;Premature atrial contractions (PACs) are a common cardiac dysrhythmia characterized by premature heartbeats originating in the atria While the SA node (sinoatrial node) typically paces the heart during normal sinus rhythm PACs occur when a region of the atria depolarizes before the SA node can send it's signal, and thus triggers a premature heartbeat

The P waves look abnormal in PAC, the atria do not have enough time to fill up with blood so the ventricles do not get enough blood and cardiac out and stroke volume will be decreased causing symptoms You can also see there's a little pause after the PAC and then the SA node starts up again to a normal sinus rhythm · An arrhythmia is any abnormal rhythm other than normal sinus rhythm – the baseline rhythm of the heart This can be a benign variant (like sinus arrhythmia), or it could be deadly (like ventricular fibrillation) In order to know how to read an EKG rhythm strip, you need to first be able to understand what normal sinus rhythm (NSR) looks likeThere are 6 different sinus arrhythmia A normal heart should have a normal sinus rhythm, this rhythm can be identified by a ventricular rate of bpm, at a regular rate, with a normal PR interval (012 to 0 second) and a normal QRS complex (012 second and less)
