Persistent inappropriate sinus tachycardia after radiofrequency ablation of left lateral accessory pathway

, 2015
A patient with palpitations and narrow QRS tachycardia was evaluated. In the EP study an atrioventricular reentrant tachycardia mediated by a left lateral accessory pathway was identified and catheter ablation was performed with success. A week later she

Response to equine cardiac adverse events during sports

Equine Veterinary Education, EarlyView.
Summary Cardiac adverse events and sudden death are a feared scenario for equine veterinarians, with serious consequences for animal health, riders' safety and the social licence to operate equestrian sports. The response to equine cardiac adverse events (CAEs) during sports is poorly defined.

Case Report: Pseudo-wide QRS complex tachycardia in an infant with complex congenital heart disease

Frontiers in Pediatrics
The initial electrocardiogram (ECG) of a 5-month-old infant with complex congenital heart disease (pulmonary valvular stenosis, ventricular septal defects, and patent ductus arteriosus) revealed a regular wide QRS tachycardia at 169 bpm, initially ...

Mitral regurgitation and decompensated heart failure in a young pregnant pony mare: An aetiological challenge

Equine Veterinary Education, EarlyView.
Summary A 4‐year‐old, 6‐month pregnant, Welsh pony mare presented with severe acute clinical signs including depression, anorexia, pale mucous membranes, tachycardia with a grade 4/6 holosystolic murmur and moderate expiratory dyspnoea with diffuse wheezes. There was no evidence of placentitis or fetal distress.

Hamman's crunch—A pathognomonic sign of pneumomediastinum

Equine Veterinary Education, EarlyView.
Summary Pneumomediastinum, particularly spontaneous pneumomediastinum, is uncommon and presents a diagnostic challenge. In human medicine, auscultation of Hamman's crunch, a crepitant, crunching noise, audible over the cardiac region in synchrony with the heartbeat, is considered pathognomonic for pneumomediastinum.

Changes in spontaneous sinus node rate as an estimate of cardiac autonomic tone during stable and unstable ventricular tachycardia

, 1989
Changes in sinus node rate were measured as an estimate of reflex control of cardiac autonomic tone during 32 episodes of stable ventricular tachycardia (without loss of consciousness) and 21 episodes of unstable ventricular tachycardia (loss of ...

Acute and sudden death secondary to cardiac tamponade during anaesthetic recovery in a 21‐year‐old draught mule

Equine Veterinary Education, EarlyView.
Summary This case report is of educational value and contributes to the literature because it describes a unique death after anaesthesia due to cardiac tamponade from a rare cardiac neoplasm. In trying to diagnose the origin of chronic sinusitis, a geriatric mule mare was anaesthetised and during recovery, died acutely.

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-

Catheter Ablation: Evolution and Efficiencies

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT The present review includes a discussion the goals and pitfalls of efficiency in the medical profession, a historical perspective on the evolution of catheter ablation in the field of electrophysiology (EP), and the data regarding the relationship between efficiency and outcomes in the EP lab. Focus on efficacy is critical to maximize resource

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.
