Action Potentials


I have read and listened to so many explanations of action potentials and it is not a nice topic and the subject is very dull and explained in a very similar way all the time. If you do want a more clinical explanation then just google action potentials and you will be inundated.

I am going to attempt to use an analogy to explain the cycle the heart cells go through and hopefully this will make things a little more digestible and memorable.... wish me luck. The heart cell cycle has 4 stages.

Having written many posts on pacemakers, it suddenly dawned on me that I had not fully covered heart blocks. This seems crazy now as people with 'heart block' make up huge percentage of those with pacemakers.

During each heartbeat an electrical signal moves like a wave through the heart's cells causing the heart muscle cells to contract (shorten)...

Cardiology Made Easy -THE PAD: Cardiology VERY Basic ECG/EKG - Electrocardiogram - Electrokardiogram

Cardiology Made Easy -THE PAD: Cardiology VERY Basic ECG/EKG - Electrocardiogram - Electrokardiogram | World Cardiology News - www.thepad.pm | Scoop.it
ECG is simply a graph of the hearts electrical activity. Patients do not really need to know how to precisely read an ECG, obviously it would be great if we were all able to analyse the results of any test we ever went for. However I am going to give you a very basic understanding of an ECG because it will help you to understand some of the images I use in my material.
Carl Robinson's insight:

We now know that electrical energy floods through the hearts cells during a heart beat, during an ECG this electrical activity is measured by electrodes (stickers) stuck on the patients skin. The ECG machine then plots this electrical activity on a graph.

Heart Beat Under The Microscope - Lesson Two - Action Potentials

This is the second post in a series on how the heart beats on a cellular level. The first post on cells and electrical charge is available here (I would recommend reading it first). This next post is on action potentials.

In cells an action potential is the sudden changing of the cells membrane potential (electrical charge).

This change in the cells electrical charge is important as it helps control which ions (electrically charged particles) can pass in and out of the cell.

Particular ions entering the cell are the trigger that make it contract. I will explain how in the next post, but first let us have a look at how the charge of the heart muscle cell (cardiomyocyte) is able to alter over and over again.

Cardiology Made Easy -THE PAD: How Atrial Fibrillation Causes Blood Clots

Cardiology Made Easy -THE PAD: How Atrial Fibrillation Causes Blood Clots | World Cardiology News - www.thepad.pm | Scoop.it

Atrial Fibrillation and blood clots explained...

Carl Robinson's insight:
How Atrial Fibrillation Causes Blood Clots
Atrial Fibrillation is an irregular heart rhythm caused by chaotic cell activity in the top chambers of the heart. In the absence of an accessory pathway (heart abnormality like WPW) it poses two main issues. Firstly the patient can feel unwell due to the affect Atrial Fibrillation has on blood circulation around the body. Some people may feel light headed or faint and others may feel very short of breath. Another potentially more dangerous risk is the formation of blood clots in the Atrium.
Blood clots are dangerous because they have the ability to block a blood vessel (in a similar way to when food blocks a kitchen sink). When this happens blood is unable to reach the tissue that particular vessel usually supplies, this can lead to damage and possibly death of tissue. This can be particularly dangerous if the tissue in question is an organ such as the brain or heart.
