Aims: To investigate the efficacy of preventive and antitachycardia pacing (ATP) in patients with symptomatic paroxysmal atrial fibrillation (AF) without bradyarrhythmias.
Methods And Results: In this randomized cross-over pilot study, we randomized 38 symptomatic paroxysmal AF patients 'without' bradyarrhythmias to atrial pacing lower rate 70 ppm and prevention and ATP therapies ON or to atrial pacing lower rate 34 ppm and prevention and ATP therapies OFF during 12 weeks with a 4 week washout period in between. The atrial lead was preferably placed in the inter-atrial septum.
Background: Calcium antagonists are widely prescribed for angina pectoris but their effect on clinical outcome is controversial. We aimed to investigate the effect of the calcium antagonist nifedipine on long-term outcome in patients with stable angina pectoris.
Methods: We randomly assigned 3825 patients with treated stable symptomatic coronary disease to double-blind addition of nifedipine GITS (gastrointestinal therapeutic system) 60 mg once daily and 3840 to placebo.
Sudden cardiac death can be described as an unexplained natural death due to a cardiac cause. It occurs within a short period, one hour or less, after onset of symptoms in a person without any prior medical history. Among the many causes of unexplained sudden cardiac death, we would like to specifically discuss arrhythmogenic right ventricular dysplasia as a rare cause in otherwise healthy and usually young individuals.
