Q

PR interval adalah dan fungsinya?

A

Durasi awal gelombang P sampai sebelum gelombang R
=> waktu antara sebelum kontraksi atrium sampai kontraksi ventrikel selesai
fungsi => biar pengisian ventrikel terisi sempurna

A

mulai dari kontraksi ventrikel sampai relaksasi ventrikel
dilakukan untuk menilai infark miokard

Q

Normalnya ritme EKG adalah

A

Sinus, yang mengomando SA node

17
Q

Kriteria ritme sinus (4)

A

Gel. P positif di lead II, III
Gel. P negatif di aVR
Morfologi selalu sama
Setiap P diikuti gel QRS

18
Q

Ritme atrium adalah

A

Ritme berasal dari impuls ektopik di atrium

19
Q

Jenis ritme atrium

A

Atrial fibrillation: gel P sulit diidentifikasi
Atrial flutter: gel P seperti gergaji

20
Q

Ritme ventrikel ditandai oleh

A
  • tidak ada gelombang P (SA dan atrium nyerah jadi yg generate listrik ventrikel) (gambar lokomotif sherwood)
  • QRS lebar” (bpm lebih rendah dari SA)
