Ahmad Handayani

Aritmia.

Merupakan keadaan dimana terdapat irama jantung yang tidak memenuhi kriteria irama yang normal (sinus ritme)

Faktor Pencetus

Underlying cardiac disease- Penyakit jantung koroner- Penyakit jantung katup- Penyakit jantung hipertensi- Penyakit jantung bawaan- Pre excitation (short of PR interval)- Long QT (congenital or acquired)

Faktor pencetus

Obat-Obatan- anti-aritmia- sympathomimetic.- B2 agonis, cocaine, anti depresants

(tricyclic), Aminophylline, caffeine.

- alcohol.

Faktor Pencetus

Metabolic abnormalities.- Electrolyte (low K, Na, Ca, Mg )- Hypoximia, Hypercarbia. - Acidosis

0 Endocrine abnormalities

-Thyrotoxicosis, Phaeochrocytoma.

Faktor pencetus

Miscellaneous.- Febrile illness- Emotional stress- Smoking- Fatigue.

Arrhytmia

Tachyarrhythmia (rate >100 x/min)

Bradyarrhytmia(rate < 60 X/min)

• QRS sempit (<0.12 ms)

• QRS lebar (>0.12 ms)

• AV blok derajat 1, 2 & 3• RBBB & LBBB
