An infarct is an obstruction of . The QRS duration is modestly prolonged at 102 ms. However, if youre performing CPR at a 30:2 compression to ventilation ratio you can see the underlying rhythm during ventilations! When the sinus node produces electrical impulses at a relatively reduced rate, the heart rate becomes slow, resulting in sinus bradycardia. If left untreated, SSS can have serious consequences for a persons health. Pacing activity may be visible or invisible, depending on e.g the type of pacemaker, intrinsic cardiac activity, etc. Sinus Rhythm: Normal Rhythm, Bradycardia, Tachycardia - Verywell Health Journal of Electrocardiology. It corresponds to the rate at which electrical pulses are sent out from the sinus node. You will frequently encounter loose lead artifact when dealing with patients who are diaphoretic because the electrodes simply will not stick to the patients body.
