Syncope versus TIA?

Global hypoperfusion versus regional ischemia

1

Orthostatic hypertension occurs from what diseases?

1. Diabetes
2. Parkinson's disease
3. Idiopathic dysautonomia

2

Usual causes of syncope?

1. Excess vagal activity
2. Orthostatic hypotension
3. Arrhythmias and cardiac outflow obstruction

3

Causes episodes of syncope precipitated by physical or emotional stress?

Vasovagal syncope

4

Prodromal signs of Vasovagal syncopic episode?

Nausea, yawning, diaphoresis

5

Activities that can cause vasovagal syncopic episodes?

Mucturition, defecation, coughing

6

Pressure over the carotid sinus can cause excess vagal activity that can result in?

Sinus bradycardia, sinus arrest, AV block (less commonly, a fall in arterial pressure without cardiac swelling)

7

Orthostatic hypotension?

Postural drop in systolic blood pressure by more than 20 it increase in pulse over 10

8

Causes of orthostatic hypotension?

1. Hypovolemia (diarrhea, vomiting, Addison's disease, hemorrhage)
2. Impaired Autonomic response (Diabetes, alcohol)
3. Iatrogenic (from antihypertensives)

9

Etiologies of cardiogenic syncope?

1. Structural (aortic stenosis, hypertrophic Obstructive cardiomyopathy)
2. PE, pulmonary hypertension
3. Arrhythmias (Bradyarrhythmias most common)

10

Sick sinus syndrome?

Tachycardia – bradycardia syndrome

Sinus bradycardia/rest alternating with supraventricular tachycardia (Usually AFIB)

11

Types of arrhythmias that are more likely to produce palpitations than syncope?

Tacky arrhythmias – afib, a-flutter, SVT, VT, VF

12

Patient with Wenckebach and low heart rate. Treatment?

Atropine
