  2. Antiarrhythmic agent - Wikipedia

    en.wikipedia.org/wiki/Antiarrhythmic_agent

    Antiarrhythmic agents, also known as cardiac dysrhythmia medications, are a class of drugs that are used to suppress abnormally fast rhythms (tachycardias), such as atrial fibrillation, supraventricular tachycardia and ventricular tachycardia. Many attempts have been made to classify antiarrhythmic agents.

  3. First-degree atrioventricular block - Wikipedia

    en.wikipedia.org/wiki/First-degree_atrio...

    The medications that most commonly cause first-degree heart block are those that increase the refractory time of the AV node, thereby slowing AV conduction. These include calcium channel blockers , beta-blockers , cardiac glycosides , and anything that increases cholinergic activity such as cholinesterase inhibitors .

  4. Pacemaker - Wikipedia

    en.wikipedia.org/wiki/Pacemaker

    A pacemaker, also known as an artificial cardiac pacemaker, is an implanted medical device that generates electrical pulses delivered by electrodes to one or more of the chambers of the heart. Each pulse causes the targeted chamber(s) to contract and pump blood, [ 3 ] thus regulating the function of the electrical conduction system of the heart .

  7. Wandering atrial pacemaker - Wikipedia

    en.wikipedia.org/wiki/Wandering_atrial_pacemaker

    Wandering atrial pacemaker may be seen in young, healthy individuals as well as in the elderly and those with lung disease. [2] The cause of wandering atrial pacemaker is unclear. Increased tone from the vagus nerve may factor into the rhythm appearing in young, healthy individuals who exercise. The vagus nerve is a part of the parasympathetic ...

  8. Transvenous pacing - Wikipedia

    en.wikipedia.org/wiki/Transvenous_pacing

    Transvenous cardiac pacing (TVP), [1] also called endocardial pacing, is a potentially life-saving intervention used primarily to correct profound bradycardia.It can be used to treat symptomatic bradycardias that do not respond to transcutaneous pacing or to drug therapy.

    Some examples include antibiotics like macrolides, diuretics, and heart medications such as anti-arrhythmic medications. [ 3 ] Additional non-cardiac causes include hemorrhage , aortic rupture , hypovolemic shock , pulmonary embolism , poisoning such as from the stings of certain jellyfish , and electrical injury .
