Transcript of Arrhythmia Recognizing heartrhythm disturbances in PSG Ann Ryckx.
Arrhyhtmia-CPR
Arrhythmias
Any change in the normal sequence of the electrical impulses from the sinus node (SA) to the ventricles can cause arrhythmia
Arrhyhtmia-CPR
P-wave: contraction of the atria
QRS-complex: contraction of the ventricles
T-wave: recovery of the ventricles
Arrhyhtmia-CPR
ECG in PSG
Mostly only 1 channelRecognition of heartrhythm
disturbances Not a diagnostic tool for other
heartpathologies s.a. signs of ischaemia
Arrhyhtmia-CPR
Atrial arrhythmia
An atrial arrhythmia is an arrhythmia caused by a dysfunction of the sinus node or the development of another atrial pacemaker within the heart tissue that takes over the rhythm of the sinus node
Arrhyhtmia-CPR
Sinus Tachykardia
A condition in which the heart rate is faster than 100 beats per minute because the sinus node is sending out electrical impulses at a rate faster than usual
Arrhyhtmia-CPR
Atrial flutter
The electrical signals come from the atria at a fast but even rate.
When the signals from the atria are coming at a faster rate than the ventricles can respond to, the ECG pattern develops a "sawtooth" pattern, showing two or more flutter waves between each QRS complex.
Arrhyhtmia-CPR
Ventricular arrhythmia
A ventricular arrhythmia is an arrhythmia caused by
a dysfunction of the sinus node an interruption in the conduction
pathways the development of another
pacemaker
Arrhyhtmia-CPR
Atrial ventricular AV Block2nd degree
Wenckebach. Progressive prolongation PR interval until a p-wave is blocked
Mobitz Type II: pr-interval constant, evt. shorter after a p-wave block
Arrhyhtmia-CPR
Atrial ventricular AV Block3d degree
No atrial impulses reach the ventricles
Possibly lifethreatening if the subsidiary pacing in the ventricles is not sufficiant
Arrhyhtmia-CPR
No circulation:No AED available
Basic Life Support
15 compressions on the chest2 breathsSame rhythm, even if 2 reanimators
Arrhyhtmia-CPR
No circulationAED available
In case of fibrillation or ventricular tachycardia connect the patient to the AED , perform analysis
Without pulse: defibrillationRepeat ABCNo result: restart BLS and defibrillation after 1
minute No fibrillation: BLS
