Can tick bites affect the heart?

As the weather warms, you may hear about more cases of Lyme disease. This condition, which spreads through tick bites, can cause a wide range of symptoms and even affect your heart if left untreated. When Lyme bacteria reach your heart tissue, it can cause Lyme carditis

Lyme carditis

Lyme carditis is a rare infection that occurs when Lyme bacteria enters your heart tissue. The bacteria affects your heart's electrical system. Your heartbeat slows, and electrical signals have trouble traveling from your heart's upper chambers to the lower chambers. Doctors call this condition heart block.

, which affects your heart's electrical system.

Can ticks go to your heart?

Lyme carditis occurs when Lyme disease bacteria enter the tissues of the heart. This can interfere with the normal movement of electrical signals from the heart's upper to lower chambers, a process that coordinates the beating of the heart.

Can Lyme cause heart problems?

“The Lyme infection causes inflammation of the heart muscle and conduction system. This can result in heart failure due to myopericarditis. It can cause heart block, bradycardia, and the patient may have symptoms of feeling faint or fainting,” she said, adding that simple fatigue may be overlooked as an indicator.

How do you know if Lyme disease has affected your heart?

The bacteria hinders your heart's electrical system, as it enters the heart tissue and can interfere with electrical signals, causing a condition called heart block. Symptoms of Lyme carditis include lightheadedness, fainting, heart palpitations, chest pains, and shortness of breath.

Can Lyme cause permanent heart damage?

The most common symptoms are light-headedness, fainting, shortness of breath, palpitations, and/or chest pain. Heart block occasionally is complete and permanent, requiring insertion of a pacemaker. Myocarditis or pericarditis may occur. Death has been reported in a few cases.

What to Do After a Tick Bite - Johns Hopkins Lyme Disease Research Center

Can tick bites cause heart palpitations?

Lyme carditis occurs when Lyme spirochete enter the tissues of the heart, causing blockage. Symptoms, which may include lightheadedness, fainting, shortness of breath, heart palpitations, or chest pain, can begin as early as one week after a tick bite.

Does Lyme carditis show up on ECG?

ECG changes and electrophysiological findings

As with viral myocarditis, changes in surface ECG are a common finding in Lyme carditis. Diffuse myocardial involvement frequently results in ST segment changes.

Does Lyme carditis go away by itself?

Can Lyme Disease Go Away on Its Own? It is possible a person with Lyme disease can clear the infection on their own, but it's better to be treated because complications that can arise are very serious. For most people, the disease and its symptoms do not resolve without treatment.

Can a tick bite cause AFIB?

Atrial fibrillation, the most common type of arrhythmia (irregular heartbeat), can increase your risk of strokes, heart disease or other heart-related complications.

Does Lyme carditis go away?

It is important to remember that most heart conduction abnormalities caused by Lyme carditis resolve with appropriate antibiotic therapy without requiring the implantation of permanent pacemakers.

Can a tick bite cause myocarditis?

Lyme carditis manifestation

[4,10] Additionally, Lyme carditis can present as myopericarditis, myocarditis, pericarditis, and rarely, endocarditis or pancarditis.

What are the symptoms of heart block?

How serious is Lyme carditis?

Doctors should consider a diagnosis of Lyme carditis in younger patients presenting with severe conduction abnormalities. Atrioventricular block can progress rapidly in Lyme carditis and be fatal. Early treatment with antibiotics may prevent irreversible conduction disease in Lyme carditis.

What causes heart ticks?

Once both ventricles fill with blood, the atrioventricular valves shut, preventing blood from moving back into the atria. This shutting of the atrioventricular valves creates the first sound of your heartbeat – the "lub."

When should you get a tick bite checked?

When to See a Doctor for a Tick Bite: If you develop flu-like symptoms days or weeks after being bitten by a tick or notice that the skin surrounding a tick bite is becoming more swollen with enlarging areas of redness, it is time to visit a doctor for evaluation and possible treatment for Lyme disease.

Can Lyme cause heart murmur?

"What you need to know about Lyme carditis." Symptoms related to Cardiac/Pulmonary: Chest pain or rib soreness, shortness of breath, heart palpitations, pulse skips, heart block, heart murmur or valve prolapse. Over 300,000 people in the USA will contract Lyme disease each year.

What is carditis of the heart?

Myocarditis is inflammation of the heart muscle (myocardium). The inflammation can reduce the heart's ability to pump blood. Myocarditis can cause chest pain, shortness of breath, and rapid or irregular heart rhythms (arrhythmias). Infection with a virus is one cause of myocarditis.

Can Lyme disease affect blood vessels?

A recent study has shown that Borrelia burgdorferi, the bacterium that causes Lyme disease, spreads throughout the body by crawling along the inside wall—the endothelium—of blood vessels.

Can Lyme cause pericardial effusion?

Abstract. Lyme disease is well known for affecting the myocardium in the form of carditis and dilated cardiomyopathy. Pericardial effusion associated with Lyme disease has not been described as yet.

What is the test for myocarditis?

There are no specific blood tests to confirm the diagnosis of myocarditis; however, an otherwise unexplained elevation in troponin (a blood test that indicates heart muscle damage) and/or electrocardiographic features of cardiac injury are supportive.

What part of the body does Lyme disease affect?

Lyme disease can affect different body systems, such as the nervous system, joints, skin, and heart.

How soon do you need antibiotics after a tick bite?

The attached tick is identified as an adult or nymphal Ixodes scapularis (deer) tick. The tick is estimated to have been attached for ≥36 hours (based upon how engorged the tick appears or the amount of time since outdoor exposure). The antibiotic can be given within 72 hours of tick removal.

How does Lyme cause heart block?

Lyme Carditis: How Spirochetes Affect the Heart

In 90% of cases, the most common consequence of Lyme carditis is heart block. Electrical signals from the upper chambers of the heart are not properly relayed to the lower chambers of the heart, which can dramatically slow down the heart rate.

What are the long term effects of Lyme disease?

Chronic symptoms of Lyme are a much longer list and may include vertigo, ringing in the ears, short-term memory loss, light and sound sensitivity, mood swings, anxiety, depression, heart palpitations, and serious cardiac problems.

Can Lyme cause chest pressure?

Lyme bacteria can invade your heart tissue, a condition called Lyme carditis. Carditis can range from mild to severe. The bacterial interference in your heart can cause chest pains, light-headedness, shortness of breath, or heart palpitations ( 23 ).
