Consumption of Caffeinated Products and Cardiac Ectopy
in patients with left ventricular dysfunction: Should it be treated?
Testing was symptom limited and was terminated if subjects reported limiting symptoms of dyspnea, fatigue, chest pain or for medical reasons including horizontal or down-sloping ST-segment depression ([greater than or equal to] 1 mm), ST segment elevation ([greater than or equal to] 1 mm in non-Q wave lead), atrial fibrillation, or supraventricular tachycardia, suggestive left bundle branch block, fall in systolic blood pressure ([greater than or equal to] 20 mm Hg), variation in diastolic pressure under stress higher than 15 mmHg, presyncope, severe arrhythmias, presence of extra systoles, ataxia or ventricular ectopy
(presence of 6 or more premature ventricular b x [min.
Direct stimulation of GPs trigger pulmonary vein ectopy
and perpetuate atrial fibrillation by reduction of PV sleeve action potential duration, and shortening of the fibrillation cycle length.
Suspicious looking cervix (leukoplakia, cervical ectopy
This association is also seen with certain cardiovascular irregularities as well as diabetes: "Subclinical magnesium and potassium deficiencies are strongly associated with increased ventricular ectopy
Citing the most recent guidelines, symptomatic bradycardia with congenital AVB has been accepted as a Class I indication for pacemaker implantation in cases such as wide QRS escape and complex ventricular ectopy
The occurrence of scrotal ectopy
is rare and may be related to abnormal migration of the gubernaculum.
and the acquisition of human papillomavirus in adolescents and young women.
Mechanical stimulation of the myocardium resulting in electrical events is well described, occurring in such circumstances as catheter-induced ectopy
during intracardiac procedures and in the production of premature ventricular depolarizations by thumping the chest during asystole .
in adolescent girls with and without human immunodeficiency virus infection.
Sinus tachycardia and increased ventricular ectopy
are reported following the application of nortriptyline.
