If the SA node does not function, or the impulse generated in the SA node is blocked before it travels down the electrical conduction system, a group of cells further down the heart will become its pacemaker. This center is typically represented by cells inside the atrioventricular node (AV node), which is an area between the atria and ventricles, within the atrial septum. If the AV node also fails, Purkinje fibers are occasionally capable of acting as the default or "escape" pacemaker. Splet11. dec. 2024 · Pacemakers are electric activity generating devices used to treat patients with slow heart rate or symptomatic heart blocks and in patients with heart failure.[1]
Heart pacemaker: MedlinePlus Medical Encyclopedia
Percussive pacing, also known as transthoracic mechanical pacing, is the use of the closed fist, usually on the left lower edge of the sternum over the right ventricle in the vena cava, striking from a distance of 20 – 30 cm to induce a ventricular beat (the British Journal of Anaesthesia suggests this must be done to raise the ventricular pressure to 10–15 mmHg to induce electrical activity). This is an old procedure used only as a life-saving means until an electrical pacemaker is brough… SpletPeacemaker. A person who brings about or promotes peace ( Matt. 5:9; 3 Ne. 12:9 ). A peacemaker may also be someone who proclaims the gospel ( Mosiah 15:11–18 ). congee pronunciation

This stunningly designed system generates electrical impulses and conducts them throughout the muscle of the heart, stimulating the heart to contract and pump blood. Spletpacemaker A group of specialized muscle fibers in the heart that send out impulses to regulate the heartbeat. If the heart's built-in pacemaker does not function properly, an artificial pacemaker may be necessary — a small electrical device that also regulates the heartbeat by sending out impulses. edgehill mortgage
