Abstract

We are demonstrating a case of a 24-year-old man presented with acute symmetrical proximal muscle weakness in both upper and lower extremities. Common causes of proximal muscle weakness included hypokalemic periodic paralysis, acquired myopathy both infection, non-infection: endocrinopathy (e.g. hypothyroidism and hyperthyroidism, drugs (steroid and alcohol). He was diagnosed with thyrotoxicosis periodic paralysis, moreover, his electrocardiography (ECG) showed atrial tachycardia with 2:1 AV conduction and transient complete AV block.
