Normal cardiac rhythm is determined by what?
The sinoatrial node is the pacemaker of the heart and determines the normal rhythm.Sinoatrial Node
The crescent-shaped pacemaker of the heart that initiates depolarization under normal conditions is the?
Sinoatrial node
What is it called when the heart beats in normal rhythm as long as it receive the correct balance of?
SA Node (Sinoatrial) responsible for initiating the heart beat pacemaker
What pacemaker of the heart initiates depolarization under normal conditions?
The primary pacemaker of the mammalian heart is the sino-atrial node. If the SA node fails, the atrioventricular node (AV node) takes over pacemaking.
Where are the cells that make up the sinoatrial node or pacemarker located?
The cells that make up the sinoatrial (SA) node, which acts as the heart's natural pacemaker, are located in the right atrium of the heart. The SA node generates electrical impulses that initiate each heartbeat by causing the heart muscle to contract.
Where does the spark that begins your heartbeat originate?
The normal heartbeat begins as an electrical impulse in the sino-atrial node (or SA node). The SA node is called the pacemaker of the heart. It is located in the R atrium, just below the entrance of the superior vena cava.
What is the main pace maker of the heart?
The primary pacemaker of a normal healthy heart is the sinus node (or SA node). It is located in the right atria of the heart.
Are the purjinke fibers the hearts pacemaker?
SA node (sinoatrial) is primary pacemaker, SV node (sinoventricular) is secondary. Purkinje fibers are the very last pacemaker on the list. If a heart gets down to firing on that it, the person is just about dead and needs IMMEDIATE medical attention. Its max rate per minute is 30. A normal heart rate is b/n 60-100 beats per minute.

Diagnosed with a complete third-degree AV heart block to restore normal rhythm the cardiothoracic surgeon schedules for insertion of what?
Pacemaker The heart's natural pacemaker is the sinoatrial (SA) node. The SA node sends an electrical impulse through both atria, pausing at the atrioventricular (AV) node, which is a small mass of cardiac muscle. To restore normal rhythm in the case of a block, an artificial cardiac pacemaker can be implanted in the chest.
What device assists the heart to maintain a normal rhythm?
The device that assists the heart to maintain a normal rhythm is called a pacemaker.
What device assists the heart to maintain a normal rthythm?
A device that assists the heart to maintain a normal rhythm is called a pacemaker.
What property makes the normal pacemaker region of the heart function as a pacemaker?
The property of the normal pacemaker region is able to provide a normal setting for the heart to beat. It allows the heart to beat at a regular rate.
