Key result
Permanent artificial pacing in symptomatic patients with complete heart block was associated with a 15.2% mortality rate, compared to a 19.2% sudden death rate in unpaced minimally symptomatic patients.
Why the study?
Does permanent artificial pacing prevent sudden death in patients with complete heart block?
Cohort (n=59)
Does permanent artificial pacing prevent sudden death in patients with complete heart block?
Absolute Event Rate: 15.2% vs 19.2%
The considerable risk of sudden death in minimally symptomatic patients with complete heart block supports the use of permanent artificial pacing for persistent or recurrent high-degree AV block with related symptoms or ventricular irritability.
No takes yet. Share an insight, caveat, or question.
May support pacing in symptomatic complete heart block; leaves open survival benefit and criteria for minimally symptomatic patients.
J. HAYDEN HOLLINGSWORTH (1969) conducted a cohort in Complete heart block (n=59). Permanent artificial pacing vs. Conservative management (no initial pacemaker) was evaluated on Death. Permanent artificial pacing in symptomatic patients with complete heart block was associated with a 15.2% mortality rate, compared to a 19.2% sudden death rate in unpaced minimally symptomatic patients.
