Treatment Of Aberrant Nodal Pacemaker
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
What is atrial flutter with variable AV block with premature ventricular or aberrantly conducted complexes? is same with AV Block heart degres 1?
Can a paroxysmal atrial fibrillation and av node reentry tachycardia increase the risk for a heart attack?
SVT Is the lifetime chance of devoloping venticular fibrillation due to accesory pathway capable of anterograde conduction <1% When ecg was normal?
Wpw : Extremely low if antegrade conduction so rare ...Read more
Is this correct? "Wolff Parkinson white synd. is an electrical abnormality in the heart where an accessory pathway exists leading to rapid heart rate"
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 moreSee 1 more doctor answer
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
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 moreSee 3 more doctor answers
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?
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
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
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
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 moreSee 2 more doctor answers
