Classification of tachycardia1. Sinus tachycardiaimpulse from sinoatrial nodeheartbeat is over 100 beats / minsympathetic activity increase cause.2.Premature beatsimpulse from non-nodal cells occurs in advanceheartbeat activity occur ahead of scheduleincluding atrial and ventricular premature beats
Classification of tachycardia 1. Sinus tachycardia impulse from sinoatrial node. heartbeat is over 100 beats / min. sympathetic activity increase cause. 2. Premature beats impulse from non-nodal cells occurs in advance. heartbeat activity occur ahead of schedule including atrial and ventricular premature beats
3.Paroxysmaltachycardiaunexpectedly start or terminaterapid and regular abnormal rhythmheart beat is about 160~220 beats / minsupraventricular andventricular tachycaidia4.Atrial flutterheartbeat is about 300 beats /min in atriumIt is rapid and regular abnormal impulsecause rapid and coordinated contraction of atrium
3. Paroxysmal tachycardia unexpectedly start or terminate. rapid and regular abnormal rhythm. heart beat is about 160~220 beats / min supraventricular and ventricular tachycaidia 4. Atrial flutter heartbeat is about 300 beats /min in atrium. It is rapid and regular abnormal impulse. cause rapid and coordinated contraction of atrium
5.Atrial fibrillationfrequency of atrial abnormal impulse is 350~600beats / min.not regular, cause not coordinated vibration in the atrium6.Ventricularfluttercause rapid, weak and not effective contraction.Heartbeat is 150~250 beats / min7.Ventricularfibrillationcause rapider and not coordinated vibration inventricular fibersheartbeat is 200~500beats / min
5. Atrial fibrillation frequency of atrial abnormal impulse is 350~600 beats / min. not regular, cause not coordinated vibration in the atrium 6. Ventricular flutter cause rapid, weak and not effective contraction. Heartbeat is 150~250 beats / min. 7. Ventricular fibrillation cause rapider and not coordinated vibration in ventricular fibers. heartbeat is 200~500 beats / min
Pharmacological management of arrhythmiasuses drugs that exert effects directly on cardiaccells by inhibiting the function of specific ionchannels or by altering the autonomic input intothe heart. Recent technological advances have leadto an increase in nondrug strategies, includingandintraoperative,implantedpacemakers,defibrillation.Physicians caring for patients with arrhythmiasthetherefore must understand and appreciatebenefits and risks provided by each therapeutic
