In order to hopefully treat and prevent recurrence of irregular heartbeat we need to understand and — if possible — remove the underlying causes and risk factors. We need to ask: "What else is going on inside the body that might allow irregular heartbeat to develop?"
Accurate diagnosis of the factors behind irregular heartbeat consists of three steps:
|Multiple Chemical Sensitivity||13%||Unlikely|
|Low Carbohydrate Diet Consequences||0%||Ruled out|
|Caffeine Intoxication||0%||Ruled out|
Have you had an irregular heartbeat (arrhythmia)?
Possible responses:→ No / don't know
→ In the past only, seems resolved
→ Occasionally / somewhat
→ Often / very much so
An irregular or rapid heart beat and awareness of your heart beating are listed as possible symptoms of environmental illness.
Cardiac arrhythmia occurs in about 7% of symptomatic hemochromatosis patients.
Myocardial magnesium was measured in 8 young patients (mean age 32) with ventricular tachycardia of less than 30 seconds in duration who underwent endomyocardial biopsy. Myocardial magnesium content was lower in the 4 with cardiomyopathic and dysplastic lesions than in the 4 with inflammatory lesions (myocarditis) and 8 controls. 10gm magnesium over 24 hours caused a resolution of ventricular tachycardias and a greater than 80% reduction in ventricular extrasystoles. No response was seen in the 4 patients with inflammatory lesions. [Lancet: 1019, 1987]
Sleep apnea can also result in cardiac arrhythmias. Most often, the heart slows while the person stops breathing, and increases when the apneic episode ends. In 90% of those patients studied with nocturnal bradyarrythmia (slowed heart rate), there was no sign of heart rhythm abnormalities while awake. Bradyarrhythmias occurred only during sleep and varied considerably in frequency and severity. [American Heart Journal 2000; 139: pp.142-8]
Endurance sports such as triathlons, ultramarathon running and professional cycling have been associated with as much as a five-fold increase in the prevalence of atrial fibrillation (abnormal heart rhythms). People who are super-fit are more likely to need pacemakers in old age because exercise causes changes in the body that can disrupt electrical pulses in the heart and lead to permanent structural changes to heart muscles, causing abnormal heart rhythms.
