Such as beta-blockers, sodium channel blockers, and calcium channel blockers. Sometimes, medications given to improve the heart’s rhythm can have the reverse effect and cause arrhythmias. Medication side effects: Taking certain medications can impact a heart’s rate and rhythm. An EKG can reveal if the heart is beating out of rhythm or sequence. If one if these electrical fibers in non-functional, the result is delayed activation of that part of the heart, and the complex on the EKG will be wider than normal. Heart rhythm abnormalities: A heart typically beats in a steady rhythm. Delayed conduction: The ventricles receive their electrical signal through the right bundle, and the left anterior and posterior fascicles. Ischemia, or lack of blood flow, may also cause an abnormal ECG. This tissue will not conduct electricity as well, which can cause an abnormal ECG. Heart attack or ischemia: During a heart attack, blood flow in the heart is affected and heart tissue can begin to lose oxygen. If your electrolytes are imbalanced, you may have an abnormal ECG reading.

These include:ĭefects or abnormalities in the heart’s shape and size: An abnormal ECG can signal that one or more aspects of the heart’s walls are larger than another meaning that the heart is working harder than normal to pump blood.Įlectrolyte imbalances: Electrolytes are electricity-conducting particles in the body that help keep the heart muscle beating in rhythm. Abnormal results can signify several issues.
