Cardiac arrhythmia
Cardiac arrhythmia
A cardiac arrhythmia is any abnormal heart rate or rhythm
A cardiac arrhythmia is any abnormal heart rate or rhythm
Tachycardia When conduction is normal and the rate is greater than 100bpm, then the rhythm is called sinus tachycardia
Tachycardia When conduction is normal and the rate is greater than 100bpm, then the rhythm is called sinus tachycardia
Bradycardia When conduction is normal and the rate is smaller than 60bpm, then the rhythm is called sinus bradycardia
Bradycardia When conduction is normal and the rate is smaller than 60bpm, then the rhythm is called sinus bradycardia
Premature beats >Premature Atrial Ectopics >Premature Ventricular Ectopics >Premature Junctional Premature Beat
Premature beats ØPremature Atrial Ectopics ØPremature Ventricular Ectopics ØPremature Junctional Premature Beat
Atrial Ectopics The beat is caused by the premature contraction of a muscle within the atrial myocardium

房性期前收缩 提前出现一个变异的P波，QRS波一 般不变形（室上性），P'-R>0.12s,代偿 间歇常不完全

室性期前收缩 1.提前出现的QRS-T波群，其前无相关P波； 2.提前出现的QRS波形态异常，时限通常为 0.12s或以上； 3.ST段、T波与QRS波群主波方向相反； 4.期前收缩后可见一完全代偿间歇
