The missing P waves in wide QRS tachycardia

Frontiers in Physiology
A 57-year-old male patient presented with paroxysmal palpitations for 2 years. The patient’s blood pressure was 120/76 mmHg; his heart rate was 149 beats/min. The presenting electrocardiogram showed a wide QRS complex tachycardia with an irregular rhythm.

Severe congenital RYR1-associated myopathy complicated with atrial tachycardia and sinus node dysfunction: a case report

Italian Journal of Pediatrics, 2019
Background Cardiac arrhythmias are sometimes encountered in patients with hereditary myopathies and muscular dystrophies. Description of arrhythmias in myopathies and muscular dystrophies is very important, because arrhythmias have a strong impact on the

Postural change-dependent T-wave oversensing resulting in the administration of inappropriate shocks

Journal of Arrhythmia, 2012
A 68-year-old man with dilated cardiomyopathy (left ventricular ejection fraction, 15%) and nonsustained ventricular tachycardia received an implantable cardioverter defibrillator. Even though his cardiac status had greatly improved 2 years later after β-

Atrioventricular Node Slow‐Pathway Ablation Reduces Atrial Fibrillation Inducibility: A Neuronal Mechanism

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2016
BackgroundRadiofrequency ablation (RFA) for atrioventricular nodal reentrant tachycardia appears to reduce atrial tachycardia, which might relate to parasympathetic denervation at cardiac ganglionated plexuses.

Diagnosis and Treatment of Inappropriate Sinus Tachycardia

, 2017
Inappropriate sinus tachycardia (IST) is a syndrome of cardiac and extracardiac symptoms characterized by rapid sinus heart rate at rest (>100 bpm) or with minimal activity and disproportionate to the physiologic demands. Patients with this unique and

Challenges of device therapy for ventricular tachycardia in the rate range of sinus rhythm

, 1996
A method is described for patient-activated detection of ventricular tachycardia, under circumstances in which automatic algorithms fail. We present a case of a patient with an implanted defibrillator (Jewel PCD) who presented with symptomatic exercise ...

Arrhythmia Diagnosis Following an ICD Shock.

Indian Pacing and Electrophysiology Journal, 2001
Stored electrograms show atrial fibrillation with rapid ventricular rates (top panel). Sufficient numbers of RR intervals meet the tachycardia detection criteria initiating a train of anti-tachycardia pacing by the ICD (after the 8th electrogram in the ...

Is it really sinus tachycardia?

Journal of Community Hospital Internal Medicine Perspectives, 2011
A56-year-old male with a history of hypertension and coronary disease was admitted after complaining of mild shortness of breath and palpitations. He had undergone coronary bypass surgery 4 years prior to admission and had been followed regularly by his physicians.

Idiopathic Epicardial Ventricular Arrhythmias: Diagnosis and Ablation Technique from the Aortic Sinus of Valsalva

, 2005
Idiopathic outflow tract arrhythmias (ventricular tachycardias or symptomatic premature ventricular contractions; OT-VT/PVCs) can originate from the left ventricular (LV) epicardium (Epi-VT/PVCs), and radiofrequency (RF) energy applications from the ...
