many go unnoticed and produce no symptoms

palpitations - ranging from ³noticing´ or ³being aware´ of ones heartbeat to a sensation of the heart ³beating out of the chest´

if Q is affected (HR > 300) - lightheadedness and syncope, fainting

drugs & electrolyte imbalances - antiarrhythmic drugs, hypokalemia,imbalances of calcium and magnesium

very rapid arrhythmias u myocardial oxygen demand r ischemiaand angina

sudden death - especially in the case of an acute MI‡ mechanism differentiation from ECG very difficult to impossible
