2. Cardioversion - Wikipedia

   en.wikipedia.org/wiki/Cardioversion

   Drugs that are effective at maintaining normal rhythm after electric cardioversion can also be used for pharmacological cardioversion. Drugs like amiodarone , diltiazem , verapamil and metoprolol are frequently given before electrical cardioversion to decrease the heart rate, stabilize the patient and increase the chance that cardioversion is ...

3. Torsades de pointes - Wikipedia

   en.wikipedia.org/wiki/Torsades_de_pointes

   The most effective treatment to terminate torsades is an electrical cardioversion – a procedure in which an electrical current is applied across the heart to temporarily stop and then resynchronise the heart's cells. [23] Treatment to prevent recurrent torsades includes infusion of magnesium sulphate, [24] correction of electrolyte imbalances ...

4. Transcutaneous pacing - Wikipedia

   en.wikipedia.org/wiki/Transcutaneous_pacing

   Normal heart rate varies substantially between individuals, and many athletes in particular have a relatively slow resting heart rate. [2] In addition, the heart rate is known to naturally slow with age. It is only when bradycardia presents with signs and symptoms of shock that it requires emergency treatment with transcutaneous pacing.

5. Implantable cardioverter-defibrillator - Wikipedia

   en.wikipedia.org/wiki/Implantable_cardioverter...

   An implantable cardioverter-defibrillator (ICD) or automated implantable cardioverter defibrillator (AICD) is a device implantable inside the body, able to perform defibrillation, and depending on the type, cardioversion and pacing of the heart. The ICD is the first-line treatment and prophylactic therapy for patients at risk for sudden cardiac ...

6. Cardiac action potential - Wikipedia

   en.wikipedia.org/wiki/Cardiac_action_potential

   The action potential passes along the cell membrane causing the cell to contract, therefore the activity of the sinoatrial node results in a resting heart rate of roughly 60–100 beats per minute. All cardiac muscle cells are electrically linked to one another, by intercalated discs which allow the action potential to pass from one cell to the ...

7. Pacemaker - Wikipedia

   en.wikipedia.org/wiki/Pacemaker

   The primary purpose of a pacemaker is to maintain an even heart rate, either because the heart's natural cardiac pacemaker provides an inadequate or irregular heartbeat, or because there is a block in the heart's electrical conduction system. Modern pacemakers are externally programmable and allow a cardiologist to select the optimal pacing ...

8. Cardiac electrophysiology - Wikipedia

   en.wikipedia.org/wiki/Cardiac_electrophysiology

   Drawing of the ECG, with labels of intervals. Cardiac electrophysiology is a branch of cardiology and basic science focusing on the electrical activities of the heart.The term is usually used in clinical context, to describe studies of such phenomena by invasive (intracardiac) catheter recording of spontaneous activity as well as of cardiac responses to programmed electrical stimulation ...

9. Cardiac resynchronization therapy - Wikipedia

   en.wikipedia.org/wiki/Cardiac_resynchronization...

   Cardiac resynchronisation therapy (CRT or CRT-P) is the insertion of electrodes in the left and right ventricles of the heart, as well as on occasion the right atrium, to treat heart failure by coordinating the function of the left and right ventricles via a pacemaker, a small device inserted into the anterior chest wall.
