Arrhythmia ECGs

What arrhythmia is this?

Ventricular tachycardia

How would you describe the waves of this ECG?

1. Wide bizarre QRS

2. Monomorphic ventricular ectopic contractions

3. Absent P waves

How would you describe the rate and rhythm?

Regular rhythm with tachycardia

How would you describe the rate and rhythm?

Irregularly irregular with tachycardia

How would you describe the waves of this ECG?

1. Wide and bizarre QRS

2. Polymorphic ventricular ectopic contractions

3. Absent P waves

What is the arrhythmia?

Ventricular fibrillation

Is this a shockable arrhythmia?

Yes

What is the rhythm and rate of this ECG?

Irregularly regular with normal rate

How would you describe the waves?

1. Normal QRS

2. Weird P waves (F waves)

3. Missing QRS waves

4. Varying R-R intervals

What is the arrhythmia?

Atrial fibrillation

How would you describe the rate and rhythm?

Mostly regular with normal rate

How would you describe the waves?

One abnormal wide and bizarre QRS that came early

What is the arrhythmia?

Ventricular premature contraction

What is the rate and rhythm of this ECG?

Irregularly irregular with normal rhythm

How would you describe the waves?

Single wide and bizarre QRS's then a run of three wide and bizarre QRS waves that came early

What arrhythmia is this?

Nonsustained ventricular tachycardia (run of three VPCs)

How do you know that this run of VPCs did not start from the normal pathway in the heart?

1. There is no P waves preceding the abnormal QRS

2. QRS wave has a positive deflection first then negative which is opposite of a normal QRS

How would you treat this arrhythmia?

Lidocaine

How would you describe the waves?

Few wide and bizarre QRS's with one having the deflections reversed from the others

How would you describe the rate?

Bradycardia

What is the arrhythmia?

Multifocal ventricular premature contractions

Why is this arrhythmia scary?

The VPC in the middle goes up first which is different from the others meaning that there are at least two areas of the heart starting them so multiple areas of heart affected

What is the rate?

Bradycardia

What is this arrhythmia?

2nd degree AV block Mobitz type II high grade

What is the rate?

Bradycardia

What arrhythmia is this?

3rd degree AV block

What arrhythmia is this?

1st degree AV block

What arrhythmias are shown?

1. Premature atrial contraction on the fourth beat

2. Ventricular premature contraction couplet

What arrhythmia is shown?

Premature atrial contraction from ectopic origin on the fourth and 10th contraction

How do you know that the PAC came from an ectopic location?

Biphasic P wave means electrical activity went through an abnormal pathway

How do you know that this isn't a ventricular issue?

QRS is normal so it went through normal pathway

What arrhythmia is this?

Ventricular bigeminy

What drug could cause this?

Thiopental

What arrhythmia is this?

1. Escape beats

2. Accelerated idioventricular rhythm

What arrhythmia is this?

Accelerated idioventricular rhythm

What emergency situation could cause this arrhythmia?

GDV

What arrhythmia is this?

1. Atrial standstill

2. Junctional beats

What arrhythmia is this?

Bundle branch block

What is causing the abnormal QRS?

Conduction is traveling through a different pathway because the bundle branch is blocked

What arrhythmia is this?

Atrial flutter

What happened where the ECG changes pattern?

Vagal maneuver to slow down

Do the QRS's have P's?

Yes, the P wave is hidden in the T wave

What arrhythmia is this?

First degree AV block

What is causing this ECG?

Hyperkalemia

What is abnormal about these waves?

1. Absent P wave

2. Tall peaked T wave

3. Wide normal QRS

What is this ECG showing?

Sinus tachycardia

What is this ECG showing?

Sick sinus syndrome

What are the green sections?

Ventricular escape beats

What is the orangish section?

Long pauses of asystole

What is the pink section?

2nd degree AV block

What is the blue section?

Paroxysms of supraventricular tachycardia alternating with severe sinus bradycardia

What is shown?

Sinus tachycardia

What arrhythmia is this?

Torsades de Pointes

What arrhythmia is this?

Ventricular fibrillation

Is this shockable?

Yes

Is this shockable?

Yes

Is this shockable?

No
