Palpitations are predictive of future atrial fibrillation. An 11-year follow-up of 22,815 men and women: the Tromsø Study

Abstract

Palpitations, hypertension and BMI were predictive of future atrial fibrillation in both sexes.

Resting heart rate predicts incident myocardial infarction, atrial fibrillation, ischaemic stroke and death in the general population: the Tromsø Study

“…The circumference of the upper right arm was measured and the proper cuff size was selected out of four available. After the participants had been seated for 2 min with the cuff on, three values were taken at 1 min intervals 16. The mean value of the last two RHR measurements (in bpm) and of the last two SBP measurements (in mm Hg) was used in the present analysis.…”

“…Information from the National Causes of Death Registry and from death certificates was used to collect relevant information of fatal events from additional sources such as autopsy reports and records from nursing homes, ambulance services and general practitioners. The definition and ascertainment of incident MI,22 AF16 and ischaemic stroke23 used in the validation process have been described and are presented in detail in online supplementary material. Participants who had emigrated from Tromsø were identified through the Population Register of Norway.…”

“…Cardiovascular events may be ascertained and verified from hospital records or national registries 3 4 15 16. They may also be ascertained through interviews with survivors or their relatives, but the use of self-reported data without clinical verification may raise questions regarding the validity of diagnoses 5 11…”

A long-term evaluation of cryoballoon ablation in 205 atrial fibrillation patients: a single center experience

“…The current available data demonstrate that this type of rhythm monitoring is probably inferior to continuous monitoring with loop recorders [27,28], and therefore, some non-sustained or asymptomatic episodes of AF may not have been reported.…”

Potential Antiarrhythmic Effect of Methyl 3,4,5-Trimethoxycinnamate, a Bioactive Substance from Roots of <i>Polygalae Radix</i>: Suppression of Triggered Activities in Rabbit Myocytes

“…Particularly, the adrenergic hyperactivation connected with intense emotions and anxiety can, in itself, predispose the patient to supraventricular and/or ventricular arrhythmias. [14][15][16] Thus it is apparently interesting to test whether the bioactive components (such as M-TMCA) exhibit any antiarrhythmic effects. The present study was aimed to investigate the basic electrophysiological effects of these compounds at the cellular level.…”
