Hi I am @Angel24 and I am going to discuss about Cardiovascular and at the end of the topic I will give some questions I hope you guys answer it and give some feedbacks read until the end 🥰

Reward will be given read the "QUIZ" part of the article to know how to get it

I. Definition of terms

• C3 - our spine has 7 cervical segment located to our neck. The 3rd bone of our neck spine is called C3

• T4 - after the cervical we have the 12 Trunk segment of the spine and the 4th bone of the spine on our trunk is called T4

I. Heart 💕

• Heart is a cone shaped muscle inverted pyramid

• It is supplied by the nerve of the spinal segment C3 to T4

• Its size as a closed fist 👊

• Our heart lies in our diaphragm and between the 2 lungs

II. Heart Muscle s

• Papillary Muscle

• Pectinate Muscle

• Tuberculae Carnea

• Cordae Tendinae

III. Valves of the Heart

• Atrioventricular Valves - it is found between the atrium and the ventricle)

• 👉 Tricuspid Valve

• 👉 Mitral Valve

• Semilunar Valves - it prevents the backflow of the blood from the arteries in the inferior chambers of the heart.

• 👉 Aortic Valve

• 👉 Pulmonic Valve

IV. Conducting System

• SA node - "Sinus Node"

• 👉 It is the PRIMARY PACEMAKER of the heart

• AV node - "Junctional Node"

• AV Bundle of His

• Purkinje Fibers

• 👉 LARGEST PACEMAKER of the heart

V. Cardiac Cycle

• Rhythmic pumping action of the heart

• Systole - Ventricular Contraction

• Diastole - Ventricular Relaxation

VI. Most Common Heart Condition

Chest Pain or Discomfort or Angina

• 👉 (+) Levine Sign

• 👉 Referred pain to Jaw, shoulder, most common on left arm

• Types of angina:

• 👉 Chronic stable angina - precipitated by physical exertion

• 👉 Unstable angina - contraindicated to exercises or intense work

• 👉 Nocturnal angina - exertion (dreams)

• 👉 Prinzmetal angina - most common in women (post menopausal)

VII. Medical and Surgical Treatment

• Percutaneous Transluminal Coronary Angioplasty - catheter with balloon tip catheter

• IV stents

• Coronary Artery Bypass Graft

• Heart Transplant

To be continue....

Quiz:

I will be share SOMETHING to the 
best and complete answer and with 
feedbacks and suggestions ☺️

HAPPY DAY! $$

1. What is the Largest pacemaker of the heart?

2. What are the two valves between the atrium and the ventricle?

3. Our heart is supplied by the nerve...? Where does these nerves located?

4. What parts of the body does "Levine Sign" occur?

For great more great articles please give some feedbacks and suggestions to improve or change some contents. I will make way to give something to everyone ☺️
