ECG

Question 1

What is a sinus arrhythmia

Answer 1

a normal P followed by a QRS however with a irregular rhythm

Question 2

What is a an atrial premature complex arrhythmia

Answer 2

a P followed by QRST. Irregular rhythm with QRS earlier than expected

Question 3

What is a ventricular premature complex arrhythmia

Answer 3

P wave is not associated
Irregular rhythm
wide and bizarre
ventricular rhythm

Question 4

What is atrial fibrillation

Answer 4

no organised activity
no p waves normal
qrs complex

Question 5

what is super ventricular tachycardia

Answer 5

run of premature atrial complexes
fast heart rate 300 bpm +
P waves no visible
cardiac output increased and collapsed

Question 6

what is ventricular tachycardia

Answer 6

VPC's 
a run of 3 + VPC with a heart rate over 180bpm 
normally uniform and regular 
often pulse deficit 
life threatening

Question 7

What is accelerated idioventricular arrhythmia

Answer 7

VPC’s
normal rate but ventricular rhythm
normal uniform and regular
no treatment required

Question 8

What is a 1st degree AV block

Answer 8

Prolonged PQ interval
Electrical activity ‘held’ by the AV node for longer
due to high vagal tone
not treated.

Question 9

What is a 2nd degree AV block

Answer 9

Not all P waves get trhough and the AV node is blocked

Question 10

What is the morbitz type 1 of AV block

Answer 10

a progressive prolongation of a PQ interval before a block P wave.

Question 11

What is the morbitz type 2 of AV block

Answer 11

No change in PQ interval

due to a disease of AV node

Question 12

What is a 3rd degree AV block

Answer 12

No P wave gets through the AV node - all blocked
QRS complexes are ventricular escape beats
Wide and bizarre beats
QRS rates very slow
no medical treatment - needs pacemaker.
