Electrolyte imbalances, particularly low sodium, potassium, and magnesium, are prevalent in acute myocardial infarction complicated by arrhythmias and normalize over several days, highlighting the importance of electrolyte monitoring for prognosis.
Highlights the clinical importance of early electrolyte monitoring in AMI; leaves open whether aggressive repletion of these.
BACKGROUND term "arrhythmia" refers to any change from the normal sequence of electrical impulses. The electrical impulses may too fast, too slowly or erratically causing the heart to beat too fast, too slowly or erratically. When the heart doesn't properly, it can't pump blood effectively. When the heart doesn't pump blood effectively, the lungs, brain and all other can't work properly and may shutdown or be damaged. Normally, the heart's most rapidly firing cells are in the sinus (or sino-atrial or SA) node making that area a natural pacemaker. Under some conditions, almost all heart tissue can start an of the type that can generate a heartbeat. Cells in the heart's conduction system can fire automatically and start activity. This activity can interrupt the normal order of the heart's pumping activity. Secondary pacemakers elsewhere the heart provide a "backup" rhythm when the sinus node doesn't work properly or when impulses are blocked somewhere the conduction system. An arrhythmia occurs when the heart's natural pacemaker develops an abnormal rate or rhythm. The conduction pathway is interrupted. Another part of the heart takes over as pacemaker. aim of the study is to observe the prevalence of various electrolyte (Na, K, Cl and Mg) imbalances in complications of . AND METHODS is a prospective study in which the patient admitted with signs and symptoms of cardiac arrhythmias diagnosed clinically, 100 cases were selected over 1 year. serum magnesium, sodium and potassium levels were significantly lower in the AMI patients at baseline and gradually near normal on 4th day. K and Mg are showing significant difference between pre and post values in males and Mg significant difference between pre and post values day 1 and day 5 in females with arrhythmia. hyponatraemia is indication of worsening cardiac failure and cardiogenic shock. There is also relationship between potassium and QTc interval, so estimation of sodium, potassium, chlorine and magnesium levels in arrhythmia patients help to assess prognosis.
