WitrynaWhen the electrical impulse reaches the atrioventricular node (3), it is delayed slightly. The impulse then travels down the bundle of His (4), which divides into the right bundle branch for the right ventricle (5) and the left bundle branch for the left ventricle (5). The impulse then spreads through the ventricles, making them contract. WitrynaAtrial premature beats are ectopic beats that originate in the atria. They have a premature and abnormal-looking P wave followed by a normal QRS complex. Atrial premature beats are associated with an incomplete compensatory pause, meaning that the interval between the preceding and following sinus beats is less than two … WitrynaA pace-maker B cardiac muscles C left atrium D right ventricle Solution: Cardiac impulse (heart beat) normally originate from the pa ce-maker (SA node). rdml williams seal

WitrynaA normal ECG is an electrical representation of a normal heart beat or sinus rhythm. The cardiac action potential causing depolarization and repolarization of various cardiac tissues gives a pattern of rhythmic change in Electrocardiograph which can be used to diagnose different diseases of the Cardiovascular System(CVS) Normal Rate. The … WitrynaAn impulse ( action potential) that originates from the SA node at a relative rate of 60-100 bpm is known as a normal sinus rhythm. If SA nodal impulses occur at a rate less than 60 bpm, the heart rhythm is known as sinus bradycardia. If SA nodal impulses occur at a rate exceeding 100bpm, the consequent rapid heart rate is sinus tachycardia.
