Syncope and Atrial fibrillation in a Healthy 70-something Male

during which sinus bradycardia and arrhythmia are seen but not to a degree that produces symptoms. Thus, there is sinus bradycardia and arrhythmia sinus pauses ( which may be longlasting, ultimately leading to sinus arrest ) and SA nodal block. New slow AFib reflects a combination of these rhythm problems. second in duration.

Evaluation of atrial fibrillation using wearable device signals and home blood pressure data in the Michigan Predictive Activity & Clinical Trajectories in Health (MIPACT) Study: A Subgroup Analysis (MIPACT-AFib)

Frontiers in Cardiovascular Medicine

Of 59 participants who sent at least 1 EKG, 52 (88.1%) were in sinus rhythm, 3 (5.1%) AF, 2 (3.4%) indeterminate, and 2 (3.4%) sinus bradycardia. Of 76 participants assessed by the study team, 32 (42.1%) reported anxiety surrounding notifications. Cardiac monitor demonstrated AF in 2 of 3 participants with AF on Apple Watch EKGs.

This ECG shows sinus bradycardia with massively long QT (or QU?) Especially when present in the setting of bradycardia and syncopal episodes, this is very worrisome for high risk of lethal dysrhythmias including polymorphic ventricular fibrillation (termed Torsades when in the setting of long QT). interval, at over 600 msec.

Cardiomatics guide: Analyzing arrhythmias made easy

Cardiomatics

Sinus bradycardia – sinus rhythm below 60 bpm is a sinus bradycardia. AFIB/AFL – atrial fibrillation or atrial flutter episodes. Sinus tachycardia – sinus rhythm above 100 bpm is a sinus tachycardia. In healthy individuals occurs during exercising or strong emotions. Usually does not exceed 160 bpm.

Detection of Irregular Heart Rhythms Devices such as the Apple Watch or Fitbit Sense can detect irregular heart rhythms, including atrial fibrillation (AFib). These early warnings are critical, as AFib increases the risk of stroke and other heart-related complications.

Similar-looking wide beats #7,13,14 must also be aberrantly conducted supraventricular impulses — and since P waves are lost after beat #6 and subsequent R-R intervals are irregular — beats #7-thru-16 constitute a run of rapid AFib.
