+心臓不整脈は、「心臓不整脈」または「不整脈」とも呼ばれ、[[Cardiac cycle/ja|心拍]]が速すぎる、遅すぎる、またはそのリズムが不規則である一群の病態である。速すぎる[[heart rate/ja|心拍数]]-成人では1分間に100拍以上-は[[tachycardia/ja|頻脈]]と呼ばれる。心拍数が遅すぎる-毎分60拍以下-のは[[bradycardia/ja|徐脈]]と呼ばれる。不整脈の多くは症状を示さない。症状がある場合は、[[palpitations/ja|動悸]]、または心拍と心拍の間に間を感じることがある。より重篤な症状としては、[[presyncope/ja|ふらつき]]、[[Syncope (medicine)/ja|失神]]、[[shortness of breath/ja|息切れ]]、または[[chest pain/ja|胸痛]]がある。ほとんどの種類の不整脈は重篤ではないが、[[stroke/ja|脳卒中]]や[[heart failure/ja|心不全]]などの合併症を引き起こしやすいものもある。また、[[cardiac arrest/ja|心停止]]に至るものもある。
