Research explains how low sodium weakens the heart’s electrical signals

New research explains how low levels of the electrolyte sodium in the blood can disrupt the timing of the heartbeat in patients taking widely used rhythm-control medications such as flecainide, which is commonly prescribed for atrial fibrillation and other fast or irregular heart rhythms.

Why low sodium can make some heart rhythm drugs risky

New research from Virginia Tech has revealed why certain heart rhythm medications, like flecainide, can become risky when blood sodium levels drop. These drugs are commonly used to treat atrial fibrillation and other irregular heartbeats, but under certain conditions, they may actually disrupt the heart’s electrical signals rather than help them. Sodium is a crucial […] The post Why low sodium can make some heart rhythm drugs risky appeared firs…
