There are conflicting views regarding the incidence of paroxysmal tachycardia in pregnancy. Jensen (1938) concluded from a review of the literature that there had been only 19 cases reported up to 1938in which the diagnosis was beyond reasonable doubt, and he thought that the condition was rare during pregnancy. On the other hand, Campbell (1947) was of the opinion that paroxysmal tachycardia i...

OBJECTIVES Smartphone-enabled ECG devices have the potential to improve patient care by enabling remote ECG assessment of patients with potential and diagnosed arrhythmias. This prospective study aimed to assess the usefulness of pediatric ECG tracings generated by the AliveCor device (Oklahoma City, OK) and to assess user satisfaction. STUDY DESIGN Enrolled pediatric patients with documented...

BACKGROUND In patients with syncope and structural heart disease, syncope is suspected to be attributable to a primary cardiac arrhythmia, but little is known of its mechanism when electrophysiologic study is unremarkable. METHODS AND RESULTS We applied an implantable loop recorder in 35 patients with overt heart disease at risk of ventricular arrhythmia, because these were patients with prev...

Various Doppler-derived parameters of left atrial electrical remodeling have been demonstrated to predict recurrence of atrial fibrillation (AF) after AF ablation. The aim of this study was to compare three Doppler-derived measures of atrial conduction time in patients undergoing AF ablation, and to investigate their predictive value for successful procedure. In 32 prospectively enrolled patien...

A case is presented in which amiodarone was administered to suppress paroxysmal atrial fibrillation in a patient with an idiopathic cardiomyopathy. Eleven days after initiation of therapy with amiodarone, the patient experienced syncope and was noted to have recurrent episodes of polymorphous ventricular tachycardia. The patient was hospitalized and treated with a bolus as well as continuous in...

avnrt, (atrioventricular nodal reentry tachycardia), atrial tachycardia and atrial flutter are 3 kinds of supraventricular tachycardia, which their mechanism are explained based on reentry. a 60-years-old man is presented with all of the above-mentioned arrhythmias, responsive to intravenous injection of adenosine. radiofrequency ablation of the slow pathway territories cured all of them. there...

Cocaine, cannabis, amphetamines and marijuana are the common recreational drugs associated with ischemic and hemorrhagic strokes. The side-effects of acute cannabis intoxication include: (1) psychiatric behavioral abnormalities and increased risk of schizophrenia;[1] (2) cardiovascular tachycardia, supine hypertension, postural hypotension, myocardial infarction, paroxysmal atrial fibrillation ...
