2. Catecholaminergic polymorphic ventricular tachycardia

   en.wikipedia.org/wiki/Catecholaminergic...

   The resting 12-lead ECG is a useful test to differentiate CPVT from other electrical diseases of the heart that can cause similar abnormal heart rhythms. Unlike conditions such as long QT syndrome and Brugada syndrome, the resting 12-lead ECG in those with CPVT is generally normal. [8]

3. Cardiac stress test - Wikipedia

   en.wikipedia.org/wiki/Cardiac_stress_test

   Stress and potential cardiac damage from exercise during the test is a problem in patients with ECG abnormalities at rest or in patients with severe motor disability. Pharmacological stimulation from vasodilators such as dipyridamole or adenosine, or positive chronotropic agents such as dobutamine can be used.

4. Cardiology diagnostic tests and procedures - Wikipedia

   en.wikipedia.org/wiki/Cardiology_diagnostic...

   Electrocardiography (ECG/EKG in German vernacular. Elektrokardiogram) monitors electrical activity of the heart, primarily as recorded from the skin surface. A 12 lead recording, recording the electrical activity in three planes, anterior, posterior, and lateral is the most commonly used form.

5. Ventricular tachycardia - Wikipedia

   en.wikipedia.org/wiki/Ventricular_tachycardia

   The predisposition to this problem usually manifests on the ECG as a prolongation of the QT interval. QT prolongation may be congenital or acquired. Congenital problems include long QT syndrome and catecholaminergic polymorphic ventricular tachycardia. Acquired problems are usually related to drug toxicity or electrolyte abnormalities, but can ...

6. Electrophysiological techniques for clinical diagnosis

   en.wikipedia.org/wiki/Electrophysiological...

   Electrocardiography is the measurement of these signals. EKGs are cheap, non-invasive and provide immediate results which has allowed for their proliferation of use in medicine. EKGs can be ordered as a one-time test, or can be continuously monitored in the case of patients wearing a holter monitor and/or admitted to a telemetry unit. EKGs ...

7. Electrophysiology study - Wikipedia

   en.wikipedia.org/wiki/Electrophysiology_study

   Test of Electrical activity within the heart A cardiac electrophysiology study ( EP test or EP study ) is a minimally invasive procedure using catheters introduced through a vein or artery to record electrical activity from within the heart . [ 1 ]

8. Sudden arrhythmic death syndrome - Wikipedia

   en.wikipedia.org/wiki/Sudden_arrhythmic_death...

   A type of a deadly ventricular arrhythmia - Ventricular fibrillation pattern seen on an ECG: Specialty: Cardiology Causes: Ion channelopathies: Long QT syndrome (LQTS), Brugada syndrome, CPVT (catecholaminergic polymorphic ventricular tachycardia), PCCD (progressive cardiac conduction defect), Early repolarization syndrome, Mixed sodium channel ...

9. Afterdepolarization - Wikipedia

   en.wikipedia.org/wiki/Afterdepolarization

   Also seen in catecholaminergic polymorphic ventricular tachycardia (CPVT). Delayed afterdepolarization is also seen in myocardial infarction. Purkinje fibers which survive myocardial infarction remain partially depolarized due to its high concentration of cations. [7]
