Makna Klinis Fragmented QRS

Oleh :

dr.Jerry Marbun, Sp.JP, FIHA

Fragmented QRS atau fQRS ditandai dengan adanya spike tambahan pada kompleks QRS. Fragmented QRS dapat menandakan gangguan konduksi termasuk adanya skar miokardium, sampai dengan prediktor aritmia dan prognostik buruk pada infark miokard. Sebelumnya, kriteria fQRS terbatas pada QRS sempit (<120 ms), tetapi saat ini sudah dapat ditegakkan pada QRS lebar seperti pada bundle branch block, ventrikel ektopik, atau pada penggunaan pacemaker.[1–3]

Kriteria Diagnosis Fragmented QRS

Adanya spike untuk kriteria diagnosis fragmented QRS (fQRS) didefinisikan sebagai gelombang R’ tambahan (R’) atau takik/notching di nadir/bagian terdalam gelombang R atau S pada 2 lead berpasangan dalam EKG 12 lead. Notch atau gelombang tambahan ini yang membentuk fragmentasi pada gelombang QRS.
