Heart Attack:
The excessive amount of potassium levels in your blood can readily cause heart problems by first interfering with the normal functioning of heart muscles and then causing irregular heart beating or arrhythmias. The progression of heart problems due to higher blood potassium levels eventually results in creating a heart attack or cardiac arrest. The cardiac arrest or heart attack happens when the heart muscles are not able to supply an adequate amount of oxygen to the body, and the heart muscles eventually frustrate and stop working. The cardiac arrest happens in the fewer cases of patients in which there is prolonged hyperkalemia condition.
