What Researchers Did
The researchers studied 31 patients with ischemic heart disease and irregular heartbeats to see how hyperbaric oxygen therapy affected their condition.
What They Found
The study found that hyperbaric oxygen therapy reduced the frequency and length of irregular heartbeat episodes, leading to long-term periods without symptoms. It also decreased the number of extra heartbeats, though this effect was short-lived. Furthermore, during episodes of atrial fibrillation, HBO helped shift the heart rhythm from a very fast rate to a more normal rate, and a course of HBO therapy had a lasting positive effect on blood flow in patients with weakened heart muscle.
What This Means for Canadian Patients
For Canadian patients experiencing irregular heartbeats due to ischemic heart disease, this research suggests that hyperbaric oxygen therapy could potentially help manage their symptoms. While the study is older, it indicates a possible benefit in reducing the frequency and severity of these episodes and improving heart function. Patients should discuss all treatment options with their healthcare provider to determine the best course of action for their specific condition.
Canadian Relevance
No direct Canadian connection identified. This study does not cover a Health Canada-recognized indication for hyperbaric oxygen therapy.
Study Limitations
The study was conducted in 1981 with a small group of 31 patients, and lacked a control group for comparison.
