Arrhythmia

 What Is an Arrhythmia?

An arrhythmia, or irregular heartbeat, is a problem with the rate or rhythm of your heartbeat. Your heart may beat too quickly, too slowly, or with an irregular rhythm.

It is normal for your heart rate to speed up during physical activity and to slow down while resting or sleeping. It is also normal to feel as if your heart skips a beat occasionally. But a frequent irregular rhythm may mean that your heart is not pumping enough blood to your body. You may feel dizzy, faint, or have other symptoms. 

Arrhythmias are treatable with medicine or procedures to control the irregular rhythms. If not treated, arrhythmias can damage the heart, brain, or other organs. This can lead to life-threatening stroke, heart failure, or cardiac arrest. During cardiac arrest, the heart suddenly and unexpectedly stops beating, causing death if it is not treated within minutes.

If you have been diagnosed with an arrhythmia, your doctor may talk to you about healthy lifestyle changes you can make. You may need to avoid activities that may trigger your arrhythmia. These steps may help prevent your arrhythmia from getting worse. 




What Health Problems Can be Caused by Arrhythmias?

Arrhythmias that are not diagnosed or are left untreated can cause complications affecting your heart and brain. They may include:

  • Cardiac arrest: Arrhythmias can cause your heart to stop beating suddenly and unexpectedly.
  • Heart failure: Repeat arrhythmias cause cardiomyopathy, which can lead to heart failure. This is a serious condition that happens when your heart can’t pump enough blood to meet your body’s needs. 
  • Problems with thinking and memory: Alzheimer’s disease and vascular dementia are more common in people who have arrhythmias. This may be because arrhythmias may reduce blood flow to your brain over time.
  • Stroke: With arrhythmias, blood can pool in the upper chambers of the heart, causing blood clots to form. If a clot breaks off and travels to the brain, it can cause a stroke.
  • Sudden infant death syndrome (SIDS): If born with an inherited type of arrhythmia, your baby may have a higher risk of SIDS.
  • Worsening arrhythmias: Some arrhythmias can get worse over time or can trigger another type of arrhythmia.

  Fourier Vs Wavelet Transform What Is Fourier Transform? An idea you’ll find all over science, math and engineering is the Fourier Transform (FT) . The FT decomposes a function into simple sines and cosines (i.e, waves). In theory, any function can be represented in this way — that is, as a sum of (possibly infinite) sine and cosine functions of different amplitudes and frequencies. I’ve provided a toy example below. Here, I’ve translated the top signal from the time domain to the frequency domain. In other words, we change the x-axis from time to frequency. The way to interpret peaks in the bottom plot is that the original signal represents the sum of two simple sine waves with frequencies one and two Hz, respectively. What Is a Wavelet Transform A major disadvantage of the Fourier transform is it captures global frequency information, meaning frequencies that persist over an entire signal. This kind of signal decomposition may not serve all applications well, for example electrocard
