Takotsubo Cardiomyopathy

In this video we cover the different types of heart block as well as heart block ECG interpretation, including 1st degree, 2nd degree which has two types- Mobitz 1 or Wenckebach and Mobitz 2, as well as 3rd degree heart block also known as complete heart block. We also look at causes, symptoms and treatment options for each type of heart block. PDFs available here: https://rhesusmedicine.com/pages/cardiologyConsider subscribing (if you found any of the info useful!): https://www.youtube.com/channel/UCRks8wB6vgz0E7buP0L_5RQ?sub_confirmation=1Buy Us A Coffee!: https://www.buymeacoffee.com/rhesusmedicineTimestamps:0:00 Normal Cardiac Conduction Pathway1:07 First Degree Heart Block / 1st Degree AV Block  - ECG1:30 First Degree Heart Block  / 1st Degree AV Block -  Causes2:36 Second Degree Heart Block - Mobitz 1 / Wenckebach - ECG3:15 Second Degree Heart Block - Mobitz 1 - Causes4:01 Second Degree Heart Block - Mobitz 2 - ECG4:25 Second Degree Heart Block - Mobitz 2 - Causes5:29 Third Degree Heart Block / Complete Heart Block - ECG6:06 Third Degree Heart Block / Complete Heart Block - CausesLINK TO SOCIAL MEDIA: https://www.instagram.com/rhesusmedicine/References:Life in the Fast Lane (LITFL), 2024.

Takotsubo Cardiomyopathy, also known as Broken Heart Syndrome, Stress Cardiomyopathy or Apical Ballooning Syndrome, is a condition that impairs the heart's ability to contract effectively. Takotsubo means octopus trap in Japanese, which is the shape the left ventricle resembles in this condition. We look at Takotsubo Cardiomyopathy pathology and symptoms, diagnosis including ECG changes as well as treatment. PDFs available here: https://rhesusmedicine.com/pages/cardiologyConsider subscribing (if you found any of the info useful!): https://www.youtube.com/channel/UCRks8wB6vgz0E7buP0L_5RQ?sub_confirmation=1Timestamps:0:00 What is Takotsubo Cardiomyopathy? 0:36 Takotsubo Cardiomyopathy Pathology / Causes1:59 Takotsubo Cardiomyopathy Risk Factors2:54 Takotsubo Cardiomyopathy Symptoms3:14 Takotsubo Cardiomyopathy Diagnosis 4:14 Takotsubo Cardiomyopathy Treatment & Prognosis LINK TO SOCIAL MEDIA: https://www.instagram.com/rhesusmedicine/ReferencesAhmad, S.A., Khalid, N. & Ibrahim, M.A., 2023.
