Differentiating ventricular tachycardia from other broad complex tachycardias is important both for the management of the acute arrhythmia and for long term treatment to prevent its recurrence. In our experience ventricular tachycardia is often mistaken for supraventricular tachycardia, and clinical bias in favour of supraventricular tachycardia is strong. Ia Several arrhythmias may give rise t...

RATIONALE Sustained arrhythmias are common in postoperative and cardiac intensive care units (ICUs), but their incidence and prognosis in general ICUs have never been reported. OBJECTIVES To estimate the incidence and prognosis of sustained arrhythmias in a general ICU population. METHODS Prospective, multicenter, 1-month inception cohort study. MEASUREMENTS AND MAIN RESULTS A total of 1,...

In order to examine the association between arrhythmia and subsequent prognosis, 72-hour ambulatory electrocardiographic monitoring was performed in 86 unselected patients with hypertrophic cardiomyopathy. During monitoring 23 patients experienced at least one episode of supraventricular tachycardia and 24 had ventricular tachycardia (of whom 10 had more than three episodes). The patients were ...

Computerized arrhythmia monitors recognize only a few of the significant arrhythmias and generally fail to detect arrhythmias of supraventricular origin. This is because conventional surface leads, which are sufficient for QRS recognition, are highly inadequate for automated P-wave detection. A new two-lead system, which includes a swallowable capsule-electrode for esophageal monitoring of atri...

This paper presents a suitable and efficient implementation of a feature extraction algorithm (Pan Tompkins algorithm) on electrocardiography (ECG) signals, for detection and classification of four cardiac diseases: Sleep Apnea, Arrhythmia, Supraventricular Arrhythmia and Long Term Atrial Fibrillation (AF) and differentiating them from the normal heart beat by using pan Tompkins RR detection fo...

BACKGROUND Normal heart ventricular arrhythmia occurring during pregnancy has been previously described. Whilst there are established reports of catheter ablation to treat supraventricular arrhythmia during pregnancy, there are no reports of ablation to treat ventricular tachycardia. CASE We present the case of a 36 year old women, 31 weeks into an otherwise uncomplicated pregnancy, experienc...

Atrial fibrillation, the most common sustained cardiac arrhythmia, has a complex and multifaceted pathophysiology. The presence of a predisposing substrate, frequently encompassing atrial hypertrophy, fibrosis, and significant alterations of the extracellular matrix, is contributing to intra-atrial electric conduction delay as well as shortening and dispersion of atrial refractory periods. Trig...

Fetal tachyarrhythmia is a rare but serious disease. Without treatment, it may progress to fetal cardiac failure, hydrops fetalis and in utero fetal death. With the rapid advancement in fetal echocardiographic equipment and techniques, such arrhythmia can be diagnosed accurately during prenatal life by using M-mode echocardiogram and doppler. Prenatal control of the tachyarrhythmia can be achie...

T ACHY ARRHYTHMIAS constitute a major cause of mortality and morbidity. The most serious manifestation of cardiac arrhythmia is sudden cardiac death where the underlying rhythm is ventricular tachycardia-ventricular fibrillation (VT VF) in the vast majority of patients. I Other symptoms produced by cardiac arrhythmias are syncope, near syncope, lightheadedness, and palpitations. Although suprav...
