WebGeneral Terms: Normal sinus rhythm - heart rhythm controlled by sinus node at a rate of 60-100 beats/min; each P wave followed by QRS and each QRS preceded by a P wave. Bradycardia - a heart rate that is lower than normal. Tachycardia - a heart rate that is higher than normal. Paroxysmal - an arrhythmia that suddenly begins and ends. WebPacing activity may be visible or invisible, depending on e.g the type of pacemaker, intrinsic cardiac activity, etc. The cardinal manifestation of pacing on surface ECG is the … WebQRS complex: The electrical signal tells your ventricles to contract.
