Pacemaker (Definition)

A pacemaker is a device which sends electrical signals to the heart triggering heartbeats when needed. There are many ways to implant and configure a pacemaker; it may beat the top chambers (atria), lower chambers (ventricles) or both. Some systems stimulate both the left and right ventricles together. Pacemakers generally treat abnormally slow heart rhythms and certain ...Read more

Effect of radiofrequency ablation treatment for heart arrhythmia?

Effect of radiofrequency ablation treatment for heart arrhythmia?

Usually curative: In experts hands, the energy from radio-frequency waves can burn the abnormal electrical pathway or "short circuit" in the heart that is allowing the arrhythmia. ...Read more

What are concerns for pacemaker insertion and bundle branch block rhythm?

What are concerns for pacemaker insertion and bundle branch block rhythm?

Slow heart rate : Lbbb is abnormal when slow heart beats cause syncope and symptomatic bradycardia - rbbb alone doesnot need treatment unles sit causes additional bloks any way need evaluation prior for pm treatment with ep study. ...Read more

What is the success rate of ablation of atrial tachycardia?

Great question: It's variable depending on location (left vs right sided). Talk to the electrophysiologist who would perform to get best information specific. ...Read more

What is "intraoperative mapping atrial tachycardia"?

What is "intraoperative mapping atrial tachycardia"?

EP procedure: This is generally done in a cath lab using wires similar or pacemaker electrodes. They are inserted through blood vessels in the leg, and place into the heart. There they "read" electrical activity to determine where the abnormal conduction is taking place. Then the offending circuit can be severed using radio-frequency ablation. ...Read more

What is the survival rate with left complete bundle branch block?

What is the survival rate with left complete bundle branch block?

Depends: On the underling cause. Those with coronary artery diease or myocardial infarction have a much worse prognosis than an incidental lbbb.(left bundle branch block). ...Read more

Meaning of the diagnosis from an EKG, 12 Lead, Initial: Sinus bradycardia, Low voltage QRS, Possible Septal and Inferior infarcts, age undetermined.

Meaning of the diagnosis from an EKG, 12 Lead, Initial: Sinus bradycardia, Low voltage QRS, Possible Septal and Inferior infarcts, age undetermined.

3 things: Sinus bradycardia means the heart rate is less than 60 Low voltage QRS could be associated with many things, including obesity, emphysema, lung disease, pericardial effusion, infiltrative cardiomyopathy, etc Possible septal and inferior infarcts age undetermined: there is some evidence of possible heart attacks on the septal and inferior walls of the heart, and cannot determine the age of events ...Read more

What is the indication for surgical ablation (av node ablation) for atrial fibrillation?

What is the indication for surgical ablation (av node ablation) for atrial fibrillation?

Definitive Control: We don't generally do this with surgery, but rather with a "catheter" based procedure (wire we thread into the heart that cauterizes the av node). This procedure provides complete control of the heart rate in the lower chamber and excellent symptom control, but makes people dependent on the pacemaker that *must* be implanted with this procedure. ...Read more

Please inform me, is the dual chamber pacemaker is contraindication with atrial fibrilation? What the best pacemaker for AF people? Better ICD or PPM?

Please inform me, is the dual chamber pacemaker is contraindication with atrial fibrilation? What the best pacemaker for AF people? Better ICD or PPM?

Depends on AF??: Ask your doctor what kind of atrial fibrillation you have. If dealing with paroxysmal atrial fib. and your doctor recommended pacemaker then dual chamber pacemaker is better suitable for you. If dealing with persistent or chronic AF and you have indication for pacemaker then single chamber pacemaker. Also discuss the current medication regimen with your doctor as some medication can affect rhythm ...Read more

If av node depolarizes faster than sa node, would heart rate equal rate of av node depolarization?

If av node depolarizes faster than sa node, would heart rate equal rate of av node depolarization?

Av node: There can be competition between the sinus node and av node when the av node depolarization rate is similar to that of the sinus node. If the av node is faster than the sinus, then it can take over and cause av nodal escape rhythm the rate usually would be that of the av node, but can be more if some sinus beats get through. ...Read more

What does the surgery for atrial tachycardia involve?

Do U mean ablation?: An ablation procedure for atrial tachycardia involves placing catheters into the heart and "mapping" the heart to determine the location of the arrhythmia. Radiofrequency energy is then used to cauterize the tissue and destroy the area causing the arrhythmia. You can speak to a cardiac electrophysiologist to learn more. ...Read more

What segment of an ECG tracing represents the end of the atrial action potential?

What segment of an ECG tracing represents the end of the atrial action potential?

Ecg: The ecg represents the surface recording of electrical vectors produced by the summated electrical forces through time produced by the cells of the heart. As such there are millions of atrial action potentials summated in each portion. Roughly the end of the p wave and the rest of theQRS-T would correlate with atrial repolarization and depolarization would be present as the p wave appears ...Read more

Is synchronized cardioversion the most effective treatment for cardiac arrest?

Is synchronized cardioversion the most effective treatment for cardiac arrest?

Maybe: Synchronized cardioversion implies that a regular and organized cardiac rhythm is present. Most patients with cardiac arrest have ventricular fibrillation. Cardioversion of ventricular fibrillation does not require synchronization. In the case of ventricular tachycardia where a regular rhythm is present, synchronization is required. ...Read more
