When angina strikes, seek medical help immediately.
Tips
usage
Medical/clinical term. Most often appears in compounds: 心绞痛 (xīnjiǎotòng, angina), 肠绞痛 (chángjiǎotòng, intestinal colic), 胆绞痛 (dǎnjiǎotòng, biliary colic). The image is of pain that 'twists' (绞) — sharp and spasmodic, unlike a steady ache.
