11. Conduction system of the heart(electrics)

12. plumbing…arteries angiogram

13. electrics….ECG….

14. Normal(sinus) heart rhythm

15. 12 leads to the full ECG

16. Heart speed fast slow

17. Atrial fibrillation

18. Heart block

21. Ectopic beats

22. ventricular tachycardia/fibrillation

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

24. 26 Athlete Pulse meter Irregular heart beat Healthy heart reassure ; no meds

25. 75 Palpitations Weight loss No meds Atrial fibrillation THYROID ENLARGED TREAT THYROID

26. 32 Intermittent palpitations Healthy heart ATRIAL TACHCARDIA ABLATION cured

27. 78 BP meds for 20 years Palpitations Atrial fibrillation MEDICATION WARFARIN(or similar) ? ABLATION+PACEMAKER

28. Electrics of the heart AV Node

29. 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

30. 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

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

36. 81 Previous heart attack Heart failure Blackouts = serious problem VENTRICULAR TACHYCARDIA DEFIBRILLATOR
