Can You Wear a Heated Vest with a Pacemaker?

Heart conditions are prevalent in individuals nowadays. Bradycardia and atrial fibrillation are two of the more serious issues which are countered by the evolution of pacemakers. Observing a recent survey, it is seen that Over 1 Million pacemakers are being used to regular serious heart conditions.

As a safety measure, to keep oneself warm, many people use the layering technique to stay warm in freezing temperatures. However, with rising technology the majority population has shifted towards the use of heated apparel. Heated vests in popular demand. But this can impact the functioning of people with pacemakers regulating their heart disorders.

In rare cases, the EMI generated by the electronic components in a heated vest can interfere with the working of pacemakers. Keeping this aside, heated vests are lauded due to their extensive use in cold weathers. They utilize ultra-modern technology, but care is recommended when used with a pacemaker. 

To counter this, getting a heated vest from a vetted manufacturer of heated apparel such as SGKOW, is a premium choice. Different safety features such as low EMI emission and EMI shielding are seen in this to protect from the effects. Weather-resistance and durability are two more features that make this brand’s apparel top of the line.

This makes it the perfect fit for harsh weather conditions and northern areas. Discussing further in this article, we will elaborate the effect of a heated vest on a pacemaker and how to avoid or neutralize its effects easily.

Understanding Pacemakers

Helping control the heart rhythm pacemakers are employed.  These are small power sources that are surgically placed below the collarbone in an individual’s chest cavity. Along with solving many other disorders, Bradycardia patients can get maximum use out of this.

This term is characterized by the excessive slow heart rate of an individual which is regulated by a pacemaker. Individuals facing ventricular blockage also see maximum effects from this.  

Rundown of Pacemaker and its Workability

There are two main parts of a pacemaker. These consist of an electrical pulse generator and electrical leads. When talking about the pulse generator, it is an electrically operated device. Along with a heated vest battery, this is present in a compact metal casing.

Thin metal wires create the electrical leads within a pacemaker. A medical professional surgically placed these leads inside the patient’s heart to coordinate it with the pacemaker’s pulse generator. Through electrical impulses generated a person’s heartbeat can be monitored and streamlined with the pulse generator. In case of slow pumping, the pulse generator sends a regulated voltage signal.

The electrical leads are implanted to constantly observe the activity of the heart. Heart’s impulses can thus be monitored. This tool picks up the signals produced by the heart’s impulses. These are typically in the form of P-wave and R-wave coming from the heart’s atria and ventricles.

Now comes the functioning of the electrical leads. These help carry the signals created by the pulse generator to the heart. The medical professional placing the pacemaker in a person’s heart can pre-determine and set the fixed signal rate. The pacemaker can thus monitor the person’s natural heart rhythm and pace accordingly to create a normal heart beat.

For people with high activity levels, these pacemakers can be programmed to raise the rate of pacing. This can be modified according to their physical activity and demands.

Significance of Prevent Electromagnetic Interference With Pacemakers

Malfunctioning of pacemakers is a critical effect of Electromagnetic Fields. These indirectly affect the normal functioning of the heart. Due to this, the steady pacing of the pacemaker is interrupted. It may result in drastic effects because it raises the risk of heart-related complications.

It can hinder the pacemaker’s ability to monitor and regulate the heart’s rhythm. False alarms are a direct outcome of this electromagnetic interference. Various parts of the pacemaker are also affected by this directly. Battery drainage is something that can be observed due to this.

Maintaining a safe distance is a first call with the equipment that can potentially generate EMIs. When focusing on utilizing heated vests, looking for brands that offer safety in case of EMIs is key. SGKOW’s heated vests comply with this as they have set safety standards like low EMI emission in their apparel.
