Myocardial infarction (MI), or heart attack, is a life-threatening event in which blood flow to a section of the heart muscle is abruptly reduced or cut off. This typically occurs when a coronary artery is blocked by a blood clot due to ruptured plaque from coronary artery disease. The result is ischemia (lack of oxygen) … See Nursing Diagnoses
Tachycardia is defined as a heart rate over 100 beats per minute at rest. It can be a normal physiological response to exercise or stress, but persistent or unexplained tachycardia is a concern. When the heart beats too fast, it may not pump blood effectively, leading to decreased cardiac output and inadequate perfusion of organs. … See Nursing Diagnoses
Atrial fibrillation (AFib) is a common cardiac arrhythmia characterized by a rapid, irregular heartbeat that can reduce the heart’s pumping efficiency. In AFib, the upper chambers of the heart (atria) quiver chaotically instead of contracting effectively, leading to an “irregularly irregular” pulse. This disturbance in rhythm often results in decreased cardiac output and pooling of … See Nursing Diagnoses
Coronary artery disease (CAD), sometimes called coronary heart disease, is a progressive condition in which the coronary arteries become narrowed or blocked by atherosclerotic plaque. This reduced blood flow deprives the heart muscle of oxygen, leading to angina, arrhythmias, myocardial infarction, or long-term heart failure. For nurses and nursing students, learning how to apply a … See Nursing Diagnoses
Bradycardia Nursing Diagnosis is an essential concept for nursing students, practicing nurses, and NCLEX preparation. Bradycardia occurs when the heart rate falls below 60 beats per minute. While it may be harmless in athletes, in many patients it signals a cardiac conduction problem that can reduce perfusion, cause dizziness or fainting, and increase the risk … See Nursing Diagnoses
