Key result
Polymyositis is linked to ECG abnormalities in ~33% of patients, predominantly conduction blocks.
Why the study?
Electrocardiographic abnormalities in patients with polymyositis and their clinical associations were not well characterized.
Observational (n=77)
ECG abnormalities, particularly conduction blocks, are common in polymyositis and warrant close observation due to the risk of sudden death.
No takes yet. Share an insight, caveat, or question.
ECG screening may identify conduction defects in polymyositis; leaves open whether findings warrant routine monitoring or alter outcomes.
R. Stern (1984) conducted an observational in Polymyositis (n=77). Polymyositis was evaluated on Electrocardiographic abnormalities. Polymyositis was associated with electrocardiographic abnormalities in 32.5% of patients, most commonly left anterior hemiblock (13.0%) and right bundle-branch block (9.1%).
