A description of an acute hospital presentation with severe tachyarrhythmia requiring multiple direct current cardioversions in a 45-year-old male bodybuilder with underlying cardiomyopathy possibly caused by long-term anabolic steroid abuse and more recent thyroxine misuse is described. A review of the literature regarding the above associations was also done. This case report further adds to the literature regarding the harmful effect of androgenic anabolic steroid misuse (with the added effect of thyroxine misuse in this case) on the heart.

Gastric volvulus is a rare condition that may present with various symptoms and may occur as an acute or chronic condition. Signs and symptoms may include nausea, vomiting, abdominal pain, and chest pain. It is imperative to recognize acute gastric volvulus in a timely fashion, since a delay in diagnosis may result in foregut obstruction and increased risk of strangulation, if not recognized and treated promptly. Additionally, secondary complications that are equally life-threatening, such as cardiac arrhythmias, can occur. For this very reason, it is important to highlight gastric volvulus as a possibility when developing a differential diagnosis in patients complaining of abdominal pain. This case report describes a 73-year-old female with no past cardiac risk factors, who presented to the emergency department (ED) with symptoms of supraventricular tachycardia (SVT), intermittent diarrhea, and nausea per emergency medical services (EMS). Upon EMS arrival at the patient\'s home, her heart rate was 210 beats per minute (bpm). Despite her condition appearing to result from a cardiac condition, imaging studies found a large hiatal hernia through which the stomach had displaced. The patient\'s stomach had distended, forming a volvulus and placing pressure on thoracic organs. This case highlights a rare but potentially life-threatening cardiac arrhythmia associated with gastric volvulus.

In patients with non-sustained tachyarrhythmias, left ventricular (LV) systolic dysfunction is uncommon. The role of catheter ablation (CA) in asymptomatic patients with tachyarrhythmia remains unclear. We report a 20-year-old patient without sustained tachyarrhythmia with a left ventricular ejection fraction of 20% who underwent radiofrequency catheter ablation (RFCA) of anteroseptal accessory pathway. She achieved normalization of left ventricular systolic function noted on echocardiography performed at 4 weeks post-ablation. Our case highlights significant improvement in LV systolic function after catheter ablation of an \"asymptomatic\" ventricular pre-excitation. Current guidelines do not endorse ablating asymptomatic patients, but careful follow-up with serial echocardiograms might be warranted. Prophylactic ablation of those patients with clear evidence of LV dyssynchrony or wide left bundle branch pattern and persistent pre-excitation is worth further consideration.

BACKGROUND: Short-term maternal administration of betamimetics is a common obstetric practice with uses including tocolysis during antenatal corticosteroid administration for fetal lung maturity, intrapartum tachysystole, and prior to external cephalic version. While previous research has demonstrated adverse effects of prolonged use of maternal betamimetics, no prior documentation exists of fetal tachyarrhythmias beyond sinus tachycardia after administration of terbutaline.
METHODS: This case documents a transient fetal tachyarrhythmia consistent with presumed atrial flutter after maternal administration of terbutaline for external cephalic version. On day of life 9, the neonate presented in supraventricular tachycardia with signs of heart failure and was subsequently diagnosed with Wolff-Parkinson-White syndrome.
CONCLUSIONS: Maternal administration of terbutaline may be associated with transient fetal tachyarrhythmia. In some fetuses, this cardiac arrhythmia may predate diagnosis of an underlying cardiac disorder, warranting close follow-up after delivery.

Atrial fibrillation (AF) is rarely found in newborns and infants. It is usually associated with some underlying diseases and presents as tachyarrhythmia. Here, we describe a case of AF in a preterm neonate. Paroxysmal AF and multifocal atrial tachycardia had been observed in the postnatal dynamic electrocardiogram. Further investigations revealed patent foramen ovale, pulmonary disease, heart failure and potential viral myocarditis. After receiving antiarrhythmic therapy and supportive treatment, the neonate underwent successful cardioversion and showed favorable outcomes without any recurrence.

We report a case of fibroid uterus with Wolff-Parkinson-White (WPW) syndrome in a 48-year-old female, posted for elective hysterectomy. Patient gave history of short recurrent episodes of palpitation and electrocardiograph confirmed the diagnosis of WPW syndrome. The anaesthetic management of these patients is challenging as they are known to develop life threatening tachyarrhythmia like paroxysmal supra-ventricular tachycardia (PSVT) and atrial fibrillation (AF). Epidural anaesthesia is preferred compared to general anaesthesia to avoid polypharmacy, noxious stimuli of laryngoscopy and intubation. To deal with perioperative complications like PSVT and AF, anti-arrhythmic drugs like adenosine, beta blockers and defibrillator should be kept ready. Perioperative monitoring is essential as patients can develop complications.
