Sarma-Tachyarrythmias

Front 1

wide QRS complex with regular rhythm

Back 1

differentiate between:
1. Sinus tachycardia with bundle branch block
2. Ventricular tachycardia

Front 2

wide QRS complex with irregular rhythm

Back 2

bundle branch block with ectopic beats

Front 3

wide QRS complex with irregularly irregular rhythm

Back 3

differentiate between:
1. Ventricular fibrillation
2. Wolf Parkinson White with atrial fibrillation

Front 4

narrow (normal) QRS with regular rhythm

Back 4

differentiated between:
1. sinus tachycardia
2. supraventricular tachycardia (AV nodal reentrant tachycardia-AVNRT)
3. Atrial flutter

Front 5

narrow QRS complex with irregular rhythm

Back 5

differentiate between:
1. tachycardia with ectopic beats or some variable block
2. Multifocal atrial tachycardia (MAT)

Front 6

narrow QRS complex with irregularly irregular rhythm

Back 6

Atrial fibrillation (not rate-controlled)

Front 7

Normal impulse coming from the Sino-atrial (S-A) node.
The heart rate is >100 beats/minute.
Usually due to increased demand for increased cardiac output:
Physical exercise; anxiety; Fever; Anemia; blood loss and hypotension Heart failure etc.
May be due to day to day normal physiological response to the situations.
May be due to excess thyroid hormone or other abnormal conditions or drugs or other agents.

Back 7

sinus tachycardia

Front 8

There is a fast pathway with long recovery period.
A second slow pathway with fast recovery
This is a set up for reentry of the impulse.
most common paroxysmal tachycardia

Back 8

AVNRT

Front 9

problem originates above the ventricles
heart rate between 150-250
normal QRS; abnormal P wave morphology; regular rhythm

Back 9

paroxysmal supraventrical tachycardia (PSVT)

Front 10

250-350 beats per minute
"saw-toothed" appearance of flutter waves
AV node only able to conduct one of every 2, 3, or 4 atrial depolarizations, creating a 2:1, 3:1, or 4:1 ratio of atrial to ventricular depolarizations

Back 10

atrial flutter

Front 11

There are at least 3 different looking P waves in any given lead.
The PR interval might also be variable. Up to 3 different PR intervals may beseen in the same lead.
Ventricular rate typically varies between 100-150 bpm.
Usually associated with pulmonary disease.
irregular rhythm

Back 11

multifocal atrial tachycardia (MAT)

Front 12

many atrial foci fire rapidly, so no single depolarization spreads very far
deporlarizations from foci near the AV node conduct to the ventricles, producing an irregularly irregular ventricular rhythm
P waves are often absent

Back 12

atrial fibrillation

Front 13

wide QRS complex and tachycardia
Last > 30 seconds
Causes significant hemodynamic symptoms
Requires therapeutic intervention for termination

Back 13

sustained ventricular tachycardia

Front 14

Wide QRS complex and tachycardia
uniform and stable QRS
appearance in any given lead

Back 14

monomorphic VT

Front 15

wide QRS comples; tachycardia
continuously varying QRS
morphology and/or axis in a single lead during episode

Back 15

polymorphic VT
