The more potassium you eat the more sodium you process out of the body. Physiologically the importance of potassium in cardiac function is described by the large number of different kinds of potassium ions channels found in the heart compared to channels and membrane transport mechanisms for other ions such as sodium and calcium.

Potassium plays a vital role in keeping the heart functioning properly and in maintaining a normal blood pressure.
Potassium effects on heart. Potassium is a mineral and an electrolyte that your body needs in the proper amount to be able to function its best. Hypokalaemia of any cause can precipitate arrhythmias. Potassium is important in physiological homeostatic control of cardiac function but is also of relevance to the diseased state as potassium-related effects.
Altered levels can cause muscle weakness and in the heart they may cause an. An above normal level of potassium can interfere with proper electric signals in that muscle layer and lead to different types of heart arrhythmias. The more potassium you eat the more sodium you lose through urine.
It can even result in a heart. It also helps relax blood vessel walls which helps lower blood pressure. 10 Potassium in the Food Supply and Potassium Consumption.

It can also help control your blood pressure. Ischaemic myocardium loses potassium into the extracellular space within seconds and the cell becomes depolarized. Potassium was identified as a shortfall nutrient by the Dietary Guidelines for Americans 2010 Advisory Committee.

Potassium is a mineral that your body need to stay healthy. Potassium and sodium concentrations play a crucial role in electric signal functioning of the hearts middle thick muscle layer known as the myocardium. 78 Consuming too little potassium and too much sodium can increase your risk of heart disease and stroke.

Potassium homeostasis is important for normal cellular function and is regulated by ion-exchange pumps primarily cellular membrane-bound sodium-potassium ATPase pumps. Untreated high potassium levels in your blood can cause further heart problems. Your cardiovascular system benefits from reduced blood pressure which puts less strain on the arteries and heart.
Effect of Potassium Ions Excess potassium in the extracellular fluids causes the heart to become dilated and flaccid and also slows the heart rate. Color-box colormain How Potassium Helps.

Increasing potassium intake can reduce your risk of heart disease and stroke by lowering blood pressure. Derangements of potassium regulation often lead to neuromuscular gastrointestinal and cardiac rhythm abnormalities. Understanding the heart-healthy benefits of potassium Foods that are rich in potassium are important in managing high blood pressure HBP or hypertension because potassium lessens the effects of sodium.
In their more relaxed state your heart and arteries can function better resulting in more energy in the present and a longer life going forward.
