Which calcium channel blocker is contraindicated in sick sinus syndrome?
Non-dihydropyridines are contraindicated in those with heart failure with reduced ejection fraction, second or third-degree AV blockade, and sick sinus syndrome because of the possibility of causing bradycardia and worsening cardiac output.
Does verapamil cause sinus problems?
Both beta-adrenergic receptor antagonist drugs (beta-blockers) and non-dihydropyridine calcium-channel blockers (non-DHP CCBs), ie, diltiazem and verapamil, can cause sinus arrest or severe sinus bradycardia, and when drugs from the two classes are used together, these effects may be more than additive.
Which of the following effects of calcium channel blockers causes a reduction in blood pressure?
Calcium channel blockers are drugs used to lower blood pressure. They work by slowing the movement of calcium into the cells of the heart and blood vessel walls, which makes it easier for the heart to pump and widens blood vessels. As a result, the heart doesn’t have to work as hard, and blood pressure lowers.
Can amlodipine cause sinus bradycardia?
There is a very low reported incidence of amlodipine-induced bradycardia (0.89% of cases). Despite its infrequency, it is important to recognize amlodipine-induced bradycardia as simply discontinuing the drug will lead to complete resolution of symptoms.
Which is better beta blocker or calcium blocker?
Calcium channel blockers should be favored over beta blockers in patients with asthma (or other forms of pulmonary disease with a bronchospastic component) given the risk of exacerbating bronchospasm.
What are the most common side effects of verapamil?

What conditions does verapamil treat?
Descriptions. Verapamil is used alone or together with other medicines to treat heart rhythm problems, severe chest pain (angina), or high blood pressure (hypertension). High blood pressure adds to the workload of the heart and arteries. If it continues for a long time, the heart and arteries may not function properly.
What are the para sinuses?
The para sinuses are hollow, air-filled spaces in the bones around the nose. The sinuses are lined with cells that make mucus, which keeps the inside of the nose from drying out during breathing.
What is paranasal sinus disease?
Paranasal Sinus Disease. Paranasal sinus disease is characterized by decreased aeration, mucosal thickening, soft tissue masses (e.g., mucus retention cyst, polyp, mucocele, tumor), air-fluid levels, and demineralization or bone destruction. From: Pediatric Radiology (Third Edition), 2009. Related terms: Sinusitis; Maxillary Sinus; Frontal Sinus
How is paranasal sinus and nasal cavity cancer treated?
Surgery. Surgery (removing the cancer in an operation) is a common treatment for all stages of paranasal sinus and nasal cavity cancer. A doctor may remove the cancer and some of the healthy tissue and bone around the cancer. If the cancer has spread, the doctor may remove lymph nodes and other tissues in the neck.
What are the signs and symptoms of nasal congestion syndrome (NCS)?
In chronic inflammatory processes, nasal discharge is purulent in nature with an unpleasant putrefactive odor, periodic exacerbations of the inflammatory process are possible, pains are more diffuse, and with exacerbations are localized in the zones noted above and at the exit sites of the branches of the trigeminal nerve.
