2. Electrocardiography - Wikipedia

   en.wikipedia.org/wiki/Electrocardiography

   Use of real time monitoring of the heart in an intensive care unit in a German hospital (2015), the monitoring screen above the patient displaying an electrocardiogram and various values of parameters of the heart like heart rate and blood pressure. Electrocardiography is the process of producing an electrocardiogram (ECG or EKG[a]), a ...

3. 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 ...

4. Catheter ablation - Wikipedia

   en.wikipedia.org/wiki/Catheter_ablation

   D017115. [edit on Wikidata] Catheter ablation is a procedure that uses radio-frequency energy or other sources to terminate or modify a faulty electrical pathway from sections of the heart of those who are prone to developing cardiac arrhythmias such as atrial fibrillation, atrial flutter and Wolff-Parkinson-White syndrome.

5. Defibrillation - Wikipedia

   en.wikipedia.org/wiki/Defibrillation

   Defibrillation. Defibrillation is a treatment for life-threatening cardiac arrhythmias, specifically ventricular fibrillation (V-Fib) and non-perfusing ventricular tachycardia (V-Tach). [1][2] A defibrillator delivers a dose of electric current (often called a counter-shock) to the heart. Although not fully understood, this process depolarizes ...

6. Artificial cardiac pacemaker - Wikipedia

   en.wikipedia.org/wiki/Artificial_cardiac_pacemaker

   Specialty. Cardiology, electrophysiology. [edit on Wikidata] An artificial cardiac pacemaker, commonly referred to as simply a 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 ...

7. Cardiac conduction system - Wikipedia

   en.wikipedia.org/wiki/Cardiac_conduction_system

   The cardiac conduction system (CCS, also called the electrical conduction system of the heart) [1] transmits the signals generated by the sinoatrial node – the heart 's pacemaker, to cause the heart muscle to contract, and pump blood through the body's circulatory system. The pacemaking signal travels through the right atrium to the ...
