2. Hypercalcaemia - Wikipedia

   en.wikipedia.org/wiki/Hypercalcaemia

   Kidney stones, abnormal heart rhythm, cardiac arrest [1] [2] Causes: Primary hyperparathyroidism, cancer, sarcoidosis, tuberculosis, Paget disease, multiple endocrine neoplasia, vitamin D toxicity [1] [3] Diagnostic method: Blood serum level > 2.6 mmol/L (corrected calcium or ionized calcium) [1] [2] Treatment

3. Calcium channel blocker - Wikipedia

   en.wikipedia.org/wiki/Calcium_channel_blocker

   Calcium channel blockers (CCB), calcium channel antagonists or calcium antagonists [2] are a group of medications that disrupt the movement of calcium (Ca 2+ ) through calcium channels . [ 3 ] Calcium channel blockers are used as antihypertensive drugs , i.e., as medications to decrease blood pressure in patients with hypertension .

4. Cardiac contractility modulation - Wikipedia

   en.wikipedia.org/wiki/Cardiac_contractility...

   Heart failure is a chronic disease that usually progresses gradually. [20] The rate of progression and the degree of symptoms of the disease varies between different patients. Cardiac contractility modulation therapy aims to treat heart failure through a medium- to long-term treatment, over the course of weeks and months. [citation needed]

5. Coronary CT calcium scan - Wikipedia

   en.wikipedia.org/wiki/Coronary_CT_calcium_scan

   A coronary CT calcium scan is a computed tomography (CT) scan of the heart for the assessment of severity of coronary artery disease. Specifically, it looks for calcium deposits in atherosclerotic plaques in the coronary arteries that can narrow arteries and increase the risk of heart attack. [ 1 ]

6. Hyperkalemia - Wikipedia

   en.wikipedia.org/wiki/Hyperkalemia

   Calcium (calcium chloride or calcium gluconate) increases threshold potential through a mechanism that is still unclear, thus restoring normal gradient between threshold potential and resting membrane potential, which is elevated abnormally in hyperkalemia. A standard ampule of 10% calcium chloride is 10 mL and contains 6.8 mmol of

7. Cardiotonic agent - Wikipedia

   en.wikipedia.org/wiki/Cardiotonic_agent

   Mechanism of action of calcium sensitizers: increase sensitivity of troponin C to Ca2+ Calcium is a vital element for regulating the contraction and relaxation of the heart muscle. [6] Calcium sensitizers are medications that increase the responsiveness of heart muscle cells to calcium, enabling more forceful contractions while conserving ...
