Using His bundle electrograms and programmed ventricular stimulation, the effects of chronic amiodarone treatment on induction, morphology, and the rate of ventricular tachycardia (VT) were studied in 17 consecutive patients treated with amiodarone for control of recurrent sustained VT or ventricular ...
Training background: when you doaerobic traininglong enough, your heart will become more efficient. The capacity of your left ventricle will increase and your ventricular muscles will become stronger which leads to an increased stroke volume. That is, your heart will pump more blood per beat than...
808-2 Sudden Heart Rate Speeding and Slowing Facilitates the Inducibility of Ventricular Tachycardia in DogsWe conclude that only 1 hour of rapid pacing after 1week of bradycardia is sufficient to produce a change in myocardial responsiveness to the K + channel blocker, CsCI, and increases the ...
Treatment involves addressing the cause of sinus tachycardia. Ventricular tachycardia Ventricular tachycardia is a fast heart rate that originates in the lower chambers of the heart (ventricles). Causes of ventricular tachycardia include: Lack of coronary artery blood flow, blocking oxygen to the heart...
705-6 Post-Infarct Ventricular Tachycardia: Success Rate of Catheter Ablation1) Immediate and long term success can be achieved with aggressive radiofrequency CA in a majority of patients with sustained monomorphic VT post-infarct, even when multiple VT morphologies are present. 2) VTs with cycle ...
Figure 1(a) displays the ECG waveform associated with SCA resulting from ventricular tachycardia/fibrillation (VT/VF). The MIT-BIH Normal Sinus Rhythm Database encompasses 18 extended ECG recordings. These recordings cover subjects that include five males aged between 26 and 45, and 13 females ...
What is the drug of choice for the acute termination of paroxysmal supraventricular tachycardia: verapamil, adenosine triphosphate, or adenosine? What is the drug of choice for the acute termin- ation of paroxysmal supraventricular tachycardia: verapamil, adenosine triphosphate or adenosine? Pacing Clin....
The relationship between transmurality of ischemic scars and the heart rate of ventricular tachycardia: Scandinavian Cardiovascular Journal: Vol 49, No 5The relationship between transmurality of ischemic scars and the heart rate of ventricular tachycardia: Scandinavian Cardiovascular Journal: Vol 49, No ...
whether short-term environmental exposures associated with acute HRV changes can lead to cardiac arrhythmias in humans. This pathway, however, seems biologically plausible given that a) acute reductions or increases in HRV parameters have been associated with the onset of ventricular tachycardia [47–...
There may be infrequent instances of electromechanical dissociation (such as various heart blocks, ventricular tachycardia, etc), in which a pulse rate measured at the periphery may not be the same with the reference electrical “heart” rate61. Future evaluations using an electrocardiogram measurement...
