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.
Bradycardia, also called bradyarrhythmia, is a resting heart rate under 60 beats per minute (BPM). [1] While bradycardia can result from various pathologic processes, it is commonly a physiologic response to cardiovascular conditioning or due to asymptomatic type 1 atrioventricular block.
For symptomatic bradycardia, the usual dosage is 0.5 to 1 mg IV push; this may be repeated every 3 to 5 minutes, up to a total dose of 3 mg (maximum 0.04 mg/kg). [23] Atropine is also useful in treating second-degree heart block Mobitz type 1 (Wenckebach block), and also third-degree heart block with a high Purkinje or AV-nodal escape rhythm.
Bradycardia treatment ranges from no treatment to the insertion of a pacemaker, depending on the duration and severity of the condition. Meditation can help lower resting heart rate.

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.
Propafenone is more selective for cells with a high rate, but also blocks normal cells more than class Ia or Ib anti-arrhythmic medications. Propafenone differs from the prototypical class Ic antiarrhythmic in that it has additional activity as a beta-adrenergic blocker which can cause bradycardia and bronchospasm.
Nifedipine is also used in high-altitude medicine to treat high altitude pulmonary edema. [19] Nifedipine is one of the main choices for the treatment of Prinzmetal angina due to its vasodilating effects on the coronary arteries. [2] Other uses include painful spasms of the esophagus such as from cancer or tetanus.
