Case #1Emergency / Toxicology / Critical care

📋 Case data

Severe/refractory?Mild, hemodynamically stable

Data is taken from this pathway's reviewed node text. Work through the pathway step by step.

Step 1 / 1 · Severe/refractory?

Bradycardia + hypotension — severe/refractory?

💡 Calcium-channel blocker (verapamil/diltiazem) and beta-blocker overdose → bradycardia, hypotension, conduction block (AV block). CCBs often cause hyperglycemia (suppress insulin release); BBs may cause hypoglycemia; some BBs (propranolol) cause sodium-channel blockade with QRS widening. First ABC, ECG monitoring, check glucose.
