We all need some level of potassium in the blood, since this mineral we get from various foods allows the body to function normally. Currently, people who have suffered a heart attack are advised to check your potassium level is kept within a certain range, but a recent study questions the ceiling and suggests keeping a little lower. In this article we tell you more about this finding.

“Not too much, or so so”. This traditional, popular saying that means finding a balance is again tested in our diet. In this case it is the potassium, a mineral the body needs to function normally because, for example, helps nerves and muscles to communicate and work together, allowing nutrients to flow into cells and helps expel waste them, and to offset some of the harmful effects of sodium (salt) on blood pressure. To make matters worse, aid in protein synthesis, metabolism of carbohydrates and is essential in the heart’s electrical activity.

A recent study has shown that patients who have suffered a heart attack whose levels of potassium in the blood are maintained within a certain range, are less likely to die than those whose levels of the mineral are below or above that range. Read the rest of this entry »

Some common types of cardiac arrhythmias include:

- Sinus node dysfunction: usually produces a slow heart rate (bradycardia) or less than 50 beats per minute. The most common cause is scar tissue that develops and eventually replaces the sinus node. It is unknown why it happens. Sinus node dysfunction may also be due to coronary disease, hypothyroidism, severe liver disease, hypothermia, typhoid or other conditions. Can also be due to increased vasovagal tone, an unusual activity of the vagus nerve.

- Supraventricular tachyarrhythmias: This diverse family of cardiac arrhythmias causes rapid heartbeat (tachycardia) that originate in areas that are above the ventricles. In most cases, the fundamental problem is an abnormality of the AV node or the presence of an abnormal pathway resulting in the typical path of the signals of the heartbeat.

Its name is in full swing cardiac arrhythmia or abnormal heart rate.

In normal adults, the heart beats regularly at a frequency of 60 to 100 times per minute and pulse rate (which can be felt in the wrist, neck or other body part) coincides with the powerful contractions of the two cavities the heart’s lower chambers, called ventricles. The two upper chambers of the heart, called atria, also contract and help fill the ventricles. Read the rest of this entry »
