Lyme carditis diagnosis during a COVID-19 quarantine
Lyme carditis is a rare but serious complication of early Lyme disease. It typically causes AV conduction abnormalities in patients with the most severe and fatal cases resulting in third-degree heart block. The condition can occur in a normally healthy individual and has even been reported in children and adolescents.
A 42-year-old man from New York City received a Lyme carditis diagnosis after quarantining in upstate New York during the COVID-19 pandemic. The case is discussed in the article “A curious case of Lyme carditis in an urban hospital,” by Brissett et al. 1
“Lyme carditis was a surprise diagnosis in our hospital due to the patient’s geographical dislocation during the COVID-19 pandemic,” writes Brissett.
In an effort to remain safe during the COVID-19 pandemic, the man sheltered at an upstate New York residence. During this time, he noticed a tick bite.
Two weeks later, he was admitted to the emergency room of an NYC hospital with “progressively worsening generalized weakness, presyncope and dyspnea on exertion.”
In addition, the patient was diaphoretic (excessive sweating) and appeared anxious when admitted to the ER. “Asystole was also noted on telemetry leading to a transient loss of consciousness,” the authors explain.
The man “had marked bradycardia at 30 beats per minute and hypotension.”
Two days prior to presenting to the ER, the patient had developed a Bull’s-eye rash, which extended from his back to his thigh.
An EKG revealed third-degree heart block with ventricular escape rhythm.
Delayed Lyme carditis diagnosis worsens outcome
The patient’s condition quickly worsened, and he went into cardiac arrest.
He was resuscitated and a temporary transvenous pacemaker was implanted.
“Cardiac arrest is rare, and mortality extremely uncommon,” the authors explain. “Of the rare case fatalities reported, delay in recognition was the main factor leading to a poor outcome.”
Young and colleagues agree. “Patients with Lyme carditis often have missed or late diagnoses, which can result in unnecessary pacemaker implantations, complications, and even fatalities.”2
The patient’s test results were positive for Lyme disease on the ELISA, IgG Western blot, and IgM Western blot. Troponin and COVID-19 tests were negative.
After 3 days of treatment with IV antibiotics (ceftriaxone), EKG results were normal. He was later prescribed oral doxycycline and had a complete recovery.
“This case is unique due to its occurrence in an urban hospital where such cases are uncommon.”
“Our case highlights the rapidly progressive nature of the illness [Lyme carditis] and the rapid rate of recovery when timely intervention is instituted.”
“With appropriate use of antibiotic and temporary pacemaker placement, our patient had resolution of his symptoms and had a remarkable recovery.”

I’m in Nova Scotia, Canada, and we have had a number of cases of heart issues due to Lyme disease. I have personally spoken to two people that ended up with pacemakers and one person that received IV antibiotics. I have also heard of several others. A Freedom of Information (FOI) request for the number of Lyme carditis cases resulted in zero. A second FOI request for AV block resulted in 125 cases from 2012 to 2020; however, we don’t know how many of these were as a result of Lyme. Do you know if there is a way to find that out? A specific code to ask for?
Your comment captures the frustration when we have rely on coding databases.
I was just found out I have tachycardia abnormal ECG could that be to my Lyme disease. No one believes that I feel this bad what am I to do now 😒😒
I have patients who have cardiac disease with an underlying tick borne illness. I advise them to continue working with their cardiologist while looking for a tick-borne infection. I have Lyme disease patients with palpitations and chest pressure from their tick borne disease without underlying heart disease. I find treatment for a tick-borne infection helps these symptoms.
The problem is that chronic lyme is not recognized, only the normal lyme disease is recognized. It’s about time to accept the existence of the chronic from which is a real thing. I wish all doctors would stop denying it, so many people without medical help are suffering from it.
