1

Mx of bradycardia

Asymptomatic or HR >40 : No rx

Symptomatic or HR < 40 : atropine

2

Sick sinus syndrome definition

Sinus node dysfunction

3

Presentations of sick sinus syndrome

Bradycardia +/- arrest

Sinoatrial block

SVT alternating with bradycardia

4

Mx of sick sinus syndrome

Pace if symptomatic

5

Indications to shock pt with arrhythmia

BP < 90

Chest pain

Signs of heart failure

Reduced GCS

6

Mx of AF / atrial flutter

Shock if indicated

Rate / Rhythm control

Anticoagulation

7

When to us Rhythm control rather than Rate control for AF

Atrial structure normal

8

Rate control medication

Beta blocker / verapamil or diltiazem
Digoxin
Amiodarone

9

Rhythm control medication

Amiodarone
Flecanide

10

How to determine to give anticoagulation for AF

CHADS2 VASc

HAS-BLED

11

Use of CHADS2 VASc

Risk of clots

12

Use of AA HAS-BLED

Risk of bleeding

13

Components of CHADS2 VASc

CCF

HTN

Age > 75

DM

Stroke (2 points)

Vascular disease

Age > 65

Sex category (female)

14

Interpretation of CHADS2 VASc

0 - no rx

1 - consider anti-platelet / anti-coagulation

2 - should be on anti-coagulation

15

Components of AA HAS-BLED

Abnormal liver funcion

Abnormal renal funtion

HTN

Alcohol

Stroke

Bleeding

Labile INR

Elderly > 65

Drugs

16

Interpretation of AA HAS-BLED

1 - Low risk

2 - medium risk (can use anti-coag if needed)

3 - high risk (look for alternatives to anti-coag)

17

SVT ECG changes

Narrow complex

Regular tachy

No p waves

18

Acute mx of SVT

Shock

19

CI to verapamil use in acute SVT

If pt already on beta blocker

20

CI to adenosine

Asthma

21

Maintenance Rx for SVT

Beta blocker or verapamil

22

Examples of vagal manoeuvres

Breath holding

Valsalva manoeuvre

Carotid massage

23

VT ECG changes

Broad complex
