2. Catheter ablation - Wikipedia

   en.wikipedia.org/wiki/Catheter_ablation

   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.

3. Premature ventricular contraction - Wikipedia

   en.wikipedia.org/wiki/Premature_ventricular...

   By definition, a PVC occurs earlier than the regular normally conducted beat. Subsequently, the time between the PVC and the next normal beat is longer as the result of a compensatory pause. [ 19 ] PVCs can be distinguished from premature atrial contractions because the compensatory pause is longer following premature ventricular contractions ...

4. Ectopic beat - Wikipedia

   en.wikipedia.org/wiki/Ectopic_beat

   Ectopic beat is a disturbance of the cardiac rhythm frequently related to the electrical conduction system of the heart, in which beats arise from fibers or group of fibers outside the region in the heart muscle ordinarily responsible for impulse formation (i.e., the sinoatrial node).

   Dr. Davis emphasizes that valve damage is not only caused by poor dietary habits, explaining, “Diet is often talked about in connection to heart disease, but valve damage has different causes.

6. Radiofrequency ablation - Wikipedia

   en.wikipedia.org/wiki/Radiofrequency_ablation

   Radiofrequency ablation (RFA), also called fulguration, [1] is a medical procedure in which part of the electrical conduction system of the heart, tumor, sensory nerves or a dysfunctional tissue is ablated using the heat generated from medium frequency alternating current (in the range of 350–500 kHz).

7. Pressure–volume loop analysis in cardiology - Wikipedia

   en.wikipedia.org/wiki/Pressure–volume_loop...

   Afterload is the mean tension produced by a chamber of the heart in order to contract. It can also be considered as the ‘load’ that the heart must eject blood against. Afterload is, therefore, a consequence of aortic large vessel compliance, wave reflection, and small vessel resistance (LV afterload) or similar pulmonary artery parameters (RV afterload

8. Polyvinyl chloride - Wikipedia

   en.wikipedia.org/wiki/Polyvinyl_chloride

   The two main application areas for single-use medically approved PVC compounds are flexible containers and tubing: containers used for blood and blood components, for urine collection or for ostomy products and tubing used for blood taking and blood giving sets, catheters, heart-lung bypass sets, hemodialysis sets etc. In Europe the consumption ...

9. Premature heart beat - Wikipedia

   en.wikipedia.org/wiki/Premature_heart_beat

   A premature heart beat or extrasystole [1] is a heart rhythm disorder corresponding to a premature contraction of one of the chambers of the heart. Premature heart beats come in two different types: premature atrial contractions and premature ventricular contractions. Often they cause no symptoms but may present with fluttering in the chest or ...
