Patients with hypocalcemia due to alkalosis will present with which symptom?

In the context of hypocalcemia due to alkalosis, patients can experience a range of symptoms primarily related to neuromuscular excitability. In particular, a notable manifestation of hypocalcemia is the risk of cardiac arrhythmias. Calcium plays a critical role in cardiac muscle function, including regulating myocardial contraction and electrical conduction. When calcium levels drop, it can lead to increased myocardial excitability and changes in the electrocardiogram, such as a prolonged QT interval, which can predispose patients to various types of arrhythmias.

While muscle weakness, seizures, and neuropathy can also manifest in hypocalcemia, they are less directly linked to the acute effects of hypocalcemia caused by alkalosis on cardiac function. Muscle weakness tends to be more associated with chronic electrolyte imbalances or other conditions affecting the neuromuscular junction, and while seizures can occur due to severe hypocalcemia, the immediate threat in patients with hypocalcemia from alkalosis is often related to cardiac stability. Thus, the likelihood of arrhythmias, particularly in the acute setting, is a significant concern for patients with hypocalcemia secondary to metabolic alkalosis.
