I'm sorry but you are mad. LOL There are so many reasons for heart rhythm issues. My reasons for tachycardia (above 100) were hyperthyroidism and magnesium deficiency.
Causes of tachycardia include high blood pressure; poor blood supply to the heart muscle due to coronary artery disease (atherosclerosis), heart valve disease, heart failure, heart muscle disease (cardiomyopathy), tumours, or infections; other medical conditions such as thyroid disease, certain lung diseases, electrolyte imbalance, alcohol or drug abuse; emotional stress or drinking large amounts of alcoholic or caffeinated beverages.
