Can Vaping Cause Heart Palpitations? Expert Opinion

Many people assume that e-cigarettes (vapes) are a safer alternative to traditional smoking. However, that is not entirely true. The reality? It’s quietly damaging blood vessels, heart rhythm, and long-term resilience, often in ways worse than people realise. 

Nicotine and other harmful chemicals found in vapes can negatively affect the heart and blood vessels. If you are a vaper, you may have noticed irregular heartbeats or heart palpitations at times. This happens because nicotine stimulates the nervous system, which can increase heart rate and blood pressure. 

However, it does not affect every user in the same way. People who are more sensitive to nicotine or have underlying heart conditions may experience palpitations from time to time. Some people also report chest discomfort, dizziness, or shortness of breath after vaping. These symptoms may be signs that the heart is under stress and should not be ignored.

Let’s explore the link between vaping and heart palpitations, how it may affect cardiopulmonary health, and the warning signs you should watch for.

What is Vaping? How is it Different From Smoking?

Vaping is the use of an electronic device, such as an e-cigarette or vape pen, to inhale and exhale an aerosol. The device heats a liquid, called e-liquid, which may contain nicotine, propylene glycol, glycerol, flavourings, and other chemicals.

Traditional cigarettes create smoke through combustion, which releases tar, carbon monoxide, and thousands of harmful chemicals. Because there is no burning process, vaping may expose users to fewer toxic substances than smoking.

A recent study reveals that many vape products still contain nicotine, propylene glycol, glycerol, and other potentially harmful chemicals, which can stimulate the nervous system, raise blood pressure, disturb heart rate, and increase the risk of irregular heart rhythms in some users.

Can Vaping Cause Heart Palpitations? Effect of Nicotine on Heart Rhythm

Nicotine is a stimulant commonly found in many vape products and tobacco. When nicotine enters the body, it triggers a chain of reactions that can affect the heart within minutes. It affects the sympathetic nervous system, often known as the body’s ‘fight or flight’ response and causes the release of stress hormones such as adrenaline and noradrenaline. 

These hormones signal the heart to beat faster and pump harder. As a result, heart rate can rise, and the normal electrical rhythm of the heart may become disturbed, leading to irregular beats, fluttering sensations, or a feeling of your heart racing.

Who is More At Risk of Vaping Induced Palpitations?

Vaping does not affect everyone in the same way. Some people use vape products without experiencing any symptoms for years, while others may feel a racing, fluttering, or skipped beats while using them. You may be at a higher risk of having heart palpitations from vaping if:

• You have an existing heart condition, such as arrhythmia, hypertension, high cholesterol, coronary artery disease, or genetic heart disease.
• You are new to vaping or an occasional user
• You vape frequently or combine it with traditional smoking
• You use vape products that have high levels of nicotine
• You are sensitive to nicotine

What Dr Francesco Lo Monaco Says About Vaping and Heart Health? 

Dr Francesco Lo Monaco, Preventive Cardiologist in London, shared expert insights about the immediate and long-term impacts of vaping on heart health. Here’s what he says:

• Heart rate may rise by upto 4 beats per minute immediately after vaping.
• Blood Pressure can rise within minutes 
• Fine particles in vape aerosol may trigger inflammation and oxidative stress
• Arteries may become stiffer with time, making it harder for blood to flow efficiently.
• The inner lining of the blood vessels can become inflamed, which might cause a heart attack or stroke.
• Regular vaping may accelerate vascular ageing, even in younger adults.
• Over time, this may raise the risk of high blood pressure, arrhythmias, heart attack, or stroke.

Conclusion

Does vaping cause heart palpitations? The simple answer is, Yes, it can in some people. Vaping may disrupt the heart’s normal rhythm, causing it to beat too fast, too slow, or skip a beat, leading to heart palpitations or cardiac arrhythmias in some users. If you notice symptoms after vaping, do not ignore them. Book a consultation with Dr Francesco Lo Monaco for expert assessment, personalised advice, and support to protect your long-term heart health.
