Understanding Abnormal Heart Rhythms


An abnormal heart rhythm is when your heart beats too slowly (under 60 beats per minute) or too quickly (above 100 beats per minute) reducing heart efficiency and volume pumped to the brain and other vital organs. Atrial arrhythmias can cause serious symptoms but ventricular arrhythmias are often immediately life-threatening or fatal and they are not discussed here. Atrial Fibrillation a.k.a. AF and A Fib: the most common of heart arrhythmias which is not usually life threatening but can cause serious and life-threatening side effects, particularly formation of clots that can move to the brain and cause cerebral vascular accidents (CVA’s) a.k.a. strokes. Normally, the atrium (upper chambers of the heart) contract evenly and forcefully sending blood to the ventricles (lower chambers of the heart) to the lungs and organs but in AF, the atrium flutter instead of contract. Risk factors: Age (over 60), smoking, hypertension, heart valve disease, coronary bypass surgery, alcohol binge drinking and chronic use, obesity, sleep apnea. Go to this is a great slide show on atrial fibrillation. Bradycardia: Heart rate that is below 60 beats [...]
