5. Cardiac: • Heart block • Tachy arrhythmias • Organic Heart diseases – Aortic Stenosis • Cerebal vascular disease • Postural Syncope • Hypoglycemia • Cough/Micturition syncope • Hyper ventilation

6. Case 2 • 50 year old diabetic Female is taken for fluroscein angiogram. After FFA patient complains of generalised itching, develops breathlessness, swelling of lips and fall in blood pressure. What is your diagnosis? Drug of Choice?

17. Precipitating Factors • Infections • Tachy arrhythmias • Electrolyte disturbances • Clinical Features • Symptoms • Sudden cough •  Sweating • Pink frothy sputum

18. Signs • Dyspneic • Tachycardia • BP • Bilateral coarse creps Treatment • O2 supplementation – 100% • Sitting position –  venous return • Sedation – inj. Morphine 2-5 mg IV
