A patient prescribed spironolactone is demonstrating ECG changes and complaining of muscle weakness. The nurse realizes this patient is exhibiting signs of which electrolyte imbalance? Hypocalcemia refers to low levels of calcium in the blood, which can present with symptoms like muscle cramps, numbness, and tingling. However, this choice is not relevant to the patient's symptoms in the scenario. Hypercalcemia is an electrolyte imbalance characterized by high levels of calcium in the blood. It can lead to ECG changes and symptoms like muscle weakness, confusion, and constipation. However, this is not the correct answer in the given scenario.

Use this EKG interpretation cheat sheet that summarizes all heart arrhythmias in an easy-to-understand fashion. An EKG uses electrodes attached to the skin to detect electric currents moving through the heart. These signals are transmitted to produce a record of cardiac activity. Arrhythmia or dysrhythmia are disturbances in the normal cardiac rhythm of the heart which occur as a result of alterations within the conduction of electrical impulses. These impulses stimulate and coordinate atrial and ventricular myocardial contractions that provide cardiac output. Ever wonder how nurses and doctors can read ECG papers with ease? How do they differentiate atrial tachycardia from atrial fibrillation, or how even to know what atrial fibrillation or tachycardia is? Sinus tachycardia is a heart rate greater than beats per minute originating from the sinus node. Causes of sinus tachycardia may include exercise, anxiety , fever , drugs, anemia , heart failure , hypovolemia , and shock. Sinus tachycardia is often asymptomatic. Management, however is directed at the treatment of the primary cause. Carotid sinus pressure carotid massage or a beta-blocker may be used to reduce heart rate. It has the following characteristics. Causes may include drugs, vagal stimulation, hypoendocrine states, hypothermia , or sinus node involvement in MI. This arrhythmia may be normal in athletes as they have quality stroke volume.

Cautious use of digoxin, calcium channel blockers, and beta-adrenergic blockers. If the hyperkalemia is very severe, the QRS complex may fuse with the T-wave and form a so-called sine wave. Heart failure, COPD, thyrotoxicosis, constrictive pericarditis, ischemic heart disease, sepsispulmonary embolusrheumatic heart disease, hypertensionmitral stenosis, atrial irritation, complication of coronary bypass or valve replacement surgery, hyperkalemia ecg changes ati.

The normal cardiac action potential may be altered by electrolyte imbalance , owing to changes in intra- and extracellular electrolyte concentrations. Some electrolyte imbalances are clinically negligible from an electrophysiological standpoint , whereas others may be life-threatening. The most common and clinically most relevant electrolyte imbalances concern potassium, calcium and magnesium. Note that some patients may exhibit combined electrolyte imbalance. The ECG may be used to estimate the severity of electrolyte imbalances and to judge whether there is a risk of serious arrhythmias. This is possible because there is a correlation between the severity of electrolyte imbalance and the visible ECG changes.

Ever wonder how nurses and doctors can read ECG papers with ease? NCBI Bookshelf. Thank you for exploring our nursing exams platform. I enjoy reading and help me to remember everything. Hypercalcemia is an electrolyte imbalance characterized by high levels of calcium in the blood. To be effective, beta-2 agonists are given in much higher doses than commonly used for bronchodilation. Trusted by experts worldwide. Figure 3. Pulmonary embolism. Follow ACLS protocol for administration of atropine for symptoms of low cardiac output , dizziness, weakness, altered LOC, or low blood pressure. PR interval progressively, but only slightly, longer with each cycle until QRS complex disappears. Very useful, thanks Reply.
