Wide QRS tachycardia with right bundle branch block QRS morphology that is almost identical to that during sinus rhythm: What is the mechanism?ablationleft posterior fasciclemyocardial infarctionPurkinje fiberventricular tachycardiadoi:10.1111/jce.13610Wakabayashi, Yasushi...
Sinus bradycardia can be defined as a sinus rhythm with a resting heart rate of 60 beats per minute or less. However, few patients actually become symptomatic until their heart rate drops to less than 50 beats per minute. The action potential responsible for this rhythm arises from the sinus...
13. Starting dose: loading doses of digoxin are generally not required in stable patients with sinus rhythm. A single daily maintenance dose of 0.25 mg is commonly employed in adults with normal renal function. 初始剂量:在病情稳定伴有窦性心律时,负荷量通常不需要;地高辛浓度在成人肾功能正常者维持...
Wide complex tachycardia with atrioventricular dissociation and QRS morphology identical to that of sinus rhythm: a manifestation of bundle branch reentry All patients had had a previous myocar-dial infarction and had a dilated left ventricle. Conclusion—The presence of (a) wide complex extrasystoles...
(SA) reentrantSVT. CSM can be helpful to diagnose the atrial rhythm during atachycardiaby producingAV block. For example, CSM-induced AV block can allowatrial flutter(AFL) waves to be seen. CSM may also be helpful to cause ventriculoatrial conduction block when there is a wideQRS complex...
In normal sinus rhythm, what does the P-wave, the PR interval, QRS complex, and QT interval reflect?ECG:An ECG, or electrocardiogram, is an electrical readout of the heart which measures the electrical output of all heart chambers during cardiac cycles. This...
Wide complex tachycardia with atrioventricular dissociation and QRS morphology identical to that of sinus rhythm: a manifestation of bundle branch reentry. To determine the features that distinguish bundle branch reentry (BBR) ventricular tachycardia from a supraventricular tachycardia with aberration on the...
Each had recurrent sustained wide QRS tachycardia due to antegrade conduction through the accessory connection. Three patients underwent epicardial mapping and successful surgical division of their accessory connection. Two of the three had a second accessory connection that was also divided surgically. ...
withceftriaxoneand within 24h her heart rate rose to over 60 beats per minute and a repeat ECG showed normalsinus rhythm. The authors concluded that ciprofloxacin can be a cause of symptomatic bradycardia, prompt recognition may lead to improvements in patient care (Sanchez et al., 2022) [A]...
AI artificial intelligence; ECG electrocardiogram; NSR normal sinus rhythm; PAF paroxysmal atrial fibrillation. Full size image Discussion We analyzed the predictive value and the optimal section in an ECG for identifying AF during NSR using a deep learning algorithm. The AI-deep learning algorithm ...
