What is an EKG?

An electrocardiogram (EKG or ECG) is a test that checks for problems with the electrical activity of your heart. An EKG translates the heart’s electrical activity into line tracings on paper. The spikes and dips in the line tracings are called waves. See a picture of the EKG components and intervals .

The heart is a muscular pump made up of four chambers . The two upper chambers are called atria, and the two lower chambers are called ventricles. A natural electrical system causes the heart muscle to contract and pump blood through the heart to the lungs and the rest of the body. See a picture of the heart and its electrical system.

An electrocardiogram (EKG or ECG) is done to:

  • Check the heart’s electrical activity.
  • Find the cause of unexplained chest pain, which could be caused by a heart attack, inflammation of the sac surrounding the heart (pericarditis), or angina.
  • Find the cause of symptoms of heart disease, such as shortness of breath,dizziness, fainting, or rapid, irregular heartbeats (palpitations).
  • Find out if the walls of the heart chambers are too thick (hypertrophied).
  • Check how well medicines are working and whether they are causing side effects that affect the heart.
  • Check how well mechanical devices that are implanted in the heart, such aspacemakers, are working to control a normal heartbeat.
  • Check the health of the heart when other diseases or conditions are present, such as high blood pressure, high cholesterol, cigarette smoking, diabetes, or a family history of early heart disease.

How To Read An EKG

An EKG is a graph (thusly named an electrocardiograph) tracing the strength and direction of this electrical signal. Leads equipped with conductive goo are placed on different parts of the body allowing a view of the heart from different angles.   If the electrical activity of the heart at any given moment is traveling toward the lead being viewed, the line on the graph goes up (positive deflection).  If the electrical activity is traveling away from the lead, the line goes down (negative deflection). This graph is being traced by a stylus on a moving piece of graph paper.  In a normal healthy heart, an EKG representing one complete heartbeat looks about like the second photo:

 That first petite little hump, affectionately called the P wave, represents the electrical signal that starts in a group of cells called the Sinoatrial Node. This signal then travels through the atria (the smaller and upper two chambers of the heart) causing them to contract and push blood in to the larger and more powerful ventricles below.

The “PR Interval” segment represents a delay in the signal at another grouping of cells called the AtrioVentricular Node.  This delay allows time for the atria to completely deliver their bounty into the Ventricles. With perfect timing this signal continues through the Bundle of His.  The signal splits and speeds along down the left and right bundle branches, making its way to the Purkinje fibers and turning north again. This stimulates those Ventricular beefcakes to contract and deliver their payload to the lungs and body (if hearts had biceps, the left ventricle would be the proverbial “gun show”….it’s such a glory hog!).

The journey causing this second contraction through the ventricles is represented by the QRS portion of the EKG. The larger T wave which then finishes off our heartbeat is the repolarization of the ventricles.  I know what you’re thinking, either “what in the what now goes where?” or hopefully, “what wave represents the repolarization of the atria”?  Well, the repolarization of the atria is buried in the larger signal of the QRS and therefore not visible on the graph.

This pattern is called normal sinus rhythm.  It is the basic EKG of any normal healthy heart.  Naturally, there are variations of normal within the healthy population. For example, my boyfriend is very fit and has a *huge* R wave (hands off his big left ventricle ladies, it’s all mine!  And don’t get me started on his early repolarization…and no…being early in this case is definitely not a bad thing).

**you can read more here but please note, I DO NOT like the way the article is written for a few reasons BUT it’s one of the easiest for people (who have not taken, or who have only had high school physiology) to understand and that’s why I used it. I never want someone to be looking at something that can be explained like it’s rocket science or anything.

I haven’t posted much about this, but my cousin, Holly, is currently battling for her life. At the age of 23, three weeks after the birth of her second son, Holly suffered a heart attack. 

She has been diagnosed with Peripartum cardiomyopathy and has been in the hospital for congestive heart failure twice since then. Her father, who is a RN, left his job at the hospital to care for his daughter full time. 

Holly is currently out of the hospital, but is too weak to care for her children. Life doesn’t stop, as we all know, and things are getting tough for this family. I’m asking you guys to please help share and support this wonderful, caring family in this challenging time.

DIY Heart Healthy Syrup

Yay! The first medicine I’ve prepared for my herbal first aid cupboard is a Heart Healthy Syrup! Here’s what I did, step by step. (Warning, Image heavy post!!)

The main medicinal ingredient in this syrup is chrysanthemum. Chrysanthemum is a great overall healthy herb, it helps reduce fevers and infections and has lots of antioxidants.  It has also been known to lower blood pressure levels and increase blood flow to the heart. I’ll probably make a fever reducing syrup later on, but there are more herbs I’d like to add to that so today I focused on the heart aspect.

(**NOTE: Please do not change medication of a diagnosed illness without consulting an actual medical professional!)

Alrighty, so first you’ll need some stuff…

  • Chrysanthemum (I used dried flowers, the kind for making tea.)
  • Honey
  • Sugar
  • Water
  • Small sauce pan
  • Small strainer
  • Something to stir with. A whisk will help later on too.
  • A funnel
  • Containers for storage (I used recycled brandy bottles.)

Step 1!

Add ¼ cup of chrysanthemum and a quart (4 cups) of cold water to your sauce pan. Its important for the water to be cold or room temp so everything infuses as it heats up together. 

Step 2!

Heat on medium temp. and bring to a simmer. Simmer liquid on med-low or low (depending on your stove) and reduce it to about ½ or a pint (2 cups.) This will take awhile so be patient. The important thing is to not heat to too high too quickly.

Step 3!

Strain your mixture into a separate container. Pour back into the pot. You don’t have to, but I added food coloring at this step to tell my syrups apart more easily.

Step 4!

Add two cups of sweetener. I used one cup of sugar and one cup of honey. You can use whatever sweetener you have, agave, sugar, honey, brown sugar, even maple syrup. Some recipes will say just use one cup of sweetener especially if you’re just going to refrigerate it, but I used more as a preservative and to make it shelf safe. Add the sugar first and whisk to dissolve, then add your honey.

Step 5!

Warm over low heat and stir well for about 30 minutes. Again this will be tedious, but slow and steady wins the race, you don’t want your sugars to burn. It will thicken and reduce to about half again.

Step 6! 

You’re almost done! Use a funnel to pour the warm syrup into empty, glass containers. Leave them on the counter to cool. After they’ve cooled, don’t forget to label and date them.

Treats high blood pressure/hypertension and heart irregularities

Directions: Take one spoonful by mouth daily, or add to warm tea.

Hope you enjoyed! I’ll add my tutorial for a stomachache syrup tonight! :)

A Glue That Seals Heart Defects

The glue—which researchers showed is able to hold fast on live beating hearts—could be a gentler alternative to stitches.

Nearly a decade ago, Jeffrey Karp was playing around with a new, biodegradable polymer he’d made. He was a post-doctoral researcher at MIT. He ended up gluing together two pieces of glass… but later forgot about it. He ultimately developed the material for something else (as a scaffold for growing artificial organs, if you’re curious).
