Normal(sinus) heart rhythm

Heart speed fast slow

Atrial fibrillation

Heart block

Ectopic beats

ventricular tachycardia/fibrillation

The irregular heart beat Diagnosis and management so much depends on the patient and the underlying heart condition

26 Athlete Pulse meter Irregular heart beat Healthy heart reassure ; no meds

75 Palpitations Weight loss No meds Atrial fibrillation THYROID ENLARGED TREAT THYROID

32 Intermittent palpitations Healthy heart ATRIAL TACHCARDIA ABLATION cured

78 BP meds for 20 years Palpitations Atrial fibrillation MEDICATION WARFARIN(or similar) ? ABLATION+PACEMAKER

Electrics of the heart AV Node

Atrial fibrillation Causes:- Hypertension Age Coronary disease Valve disease Heart failure Lung disease Excess thyroid innocent Treatment >65 years: WARFARIN Medication Occasionally pacemaker <65 years Medication Ablation Occasionally: Warfarin

Atrial fibrillation Irregular heart rate Top chambers(atria) chaotic Stagnation in atria Small clots Embolise = 15% stroke/year…. Reduced by ½ with WARFARIN or NOAC

Slow pulse:heart block 86 Healthy Blackouts HR 30/min =heart block PACEMAKER

81 Previous heart attack Heart failure Blackouts = serious problem VENTRICULAR TACHYCARDIA DEFIBRILLATOR

The irregular heart beat Diagnosis and management so much depends on the patient and the underlying heart condition
