An electrophysiologist may do radiofrequency catheter ablation or cryoablation to destroy the AV node or specific areas of heart tissue responsible . Cardiac Electrophysiology Studies, Clinical Research, and NIH-sponsored Trials. This covers the coronary circulation, chambers and valves, blood flow, and la. The doctor will insert a thin tube called an electrode catheter into a blood . The normal electrical conduction in the heart allows the impulse that is generated by the sinoatrial node (SA node . Although the SA node activity sets up the heart rate, the autonomic nervous system modulates this heart rate as well as the electrical conduction and contraction of the heart. Catheter ablation is a procedure performed to treat some types of arrhythmia. Using advanced diagnostic devices and procedures in our electrophysiology . Electrical activities of the heart can be precisely measured and monitored via electrocardiography (ECG). This fibrous demarcation acts as an insulator, thereby barricading the entrance of electrical activity from the atria into the ventricles. An electrophysiology study is a minimally invasive test that studies the electrical signals of the heart to find what is causing the heart to beat too fast, too slow or irregularly and to determine the best way to treat it. • Electrocardiogram/ECG/EKG is the graphical representation of electrical events of heart • Each event has a distinctive waveform • When the cardiac impulse passes through the heart, electrical current also spreads from the heart into the adjacent tissues surrounding the heart 27. Electrical cells. The experience and skill of our Heart Rhythm Center staff make us a leader in the diagnosis and treatment of patients with atrial fibrillation, ventricular tachycardia, Wolfe Parkinson White syndrome, flutter and other abnormal heart rhythms. The cardiac cell is a polarised membrane . The sinoatrial (SA) node is the normal site of origin of the electrical impulse (action potential) that stimulates heart muscle to contract.
