Cardiologist answers Americans most frequently Googled heart health questions

People are curious about heart health — and for good reason.

Heart disease remains the leading killer of men and women in the U.S. — each year, around 695,000 people die from cardiovascular conditions, per the Centers for Disease Control and Prevention (CDC).

For American Heart Month, Dr. Martha Gulati, M.D., a leading Cedars Sinai cardiologist and president of the American Society of Preventive Cardiology, is sharing some of the most commonly googled questions about heart health, according to Google Trends.

Below are the questions — followed by the doctor’s answers.

Did you ever wondered about these issues? Take a look. 

‘What is heart arrhythmia?’

Heart arrhythmia occurs when there is an abnormality in the rhythm of the heartbeat, said Gulati. 

“This means your heart either beats too fast, a condition known as tachycardia, or too slow, also known as bradycardia, or irregularly,” she told Fox News Digital.

Arrhythmias can be triggered by genetics, stress, pre-existing heart conditions, or lifestyle habits such as smoking and poor diet. 

They can affect people of all ages, Gulati noted.

“The most common type of arrhythmia is atrial fibrillation, also known as AFib,” she said. 

“AFib is an irregular and often rapid heart rate that can increase the risk of stroke, heart failure and other heart-related complications.”

Around 12.1 million people in the U.S. are expected to have AFib by 2030, according to the CDC. 

‘What are the symptoms of heart arrhythmias?’

Heart arrhythmias can have very different symptoms depending on the type of arrhythmia, the severity, and the health of the individual, according to Gulati.

Symptoms of a cardiac episode can include chest pain, discomfort, fatigue, and dizziness.

“Although these symptoms are alarming and can certainly induce anxiety, it’s important to know when they require an urgent hospital visit,” the doctor said. 

One challenge of arrhythmia symptoms is that they can come and go, she said.

“Sometimes, a patient makes an appointment or comes to the hospital after experiencing a cardiac symptom, and, by the time they speak with a doctor, their symptoms have abated,” said Gulati. 

“It is difficult to treat patients who are no longer presenting with the symptoms they experienced, and it can be frightening or frustrating for patients who just want to understand what is going on with their bodies.”

Medical-grade personal digital health tools can help break this cycle, she said; they allow patients to access accurate, real-time heart data that they can share with their physicians. 

“For patients, these tools can provide additional peace of mind and insight into their heart health,” Gulati said. 

“For health care providers, they offer a more comprehensive understanding of a patient’s condition and enable us to potentially implement more timely interventions.”

‘What are heart palpitations?’

These are typically characterized by a rapid, fluttering, or pounding heartbeat and can often be felt in the chest, throat, or neck, according to Gulati.

Triggers of palpitations can include stress, anxiety, hormonal changes, or stimulants like caffeine.

“Heart palpitations on their own aren’t always a cause for alarm,” said Gulati. 

Patients can purchase home devices online that allow them to easily record symptoms, receive a reading, and confirm whether they are experiencing a potentially life-threatening arrhythmia, the doctor noted. 

“However, if you experience heart palpitations coupled with chest pain, fainting, or severe dizziness, it is important to seek immediate medical attention,” she added.

‘What causes heart arrhythmias?’

Heart arrhythmias can have a myriad of symptoms — plus a variety of causes.

Lifestyle habits such as activity level, diet, or smoking can have a serious impact on overall wellness, particularly heart health, Gulati noted. 

“As health care providers, we stress the importance of a good diet and daily exercise, because it keeps your heart in good shape and reduces the risk of heart disease,” she said.

Some uncontrollable factors can contribute to arrhythmias, however.

“One of these is abnormalities in the heart structure, which tend to be congenital, meaning something you’re born with,” Gulati told Fox News Digital. 

“Congenital heart conditions can impact the way electrical activity signals travel through the heart, which can then impact the heart’s rhythm.”

Age-related changes can also make people more susceptible.

“As we age, our hearts change,” the doctor said. “These age-related changes, though natural, can affect the way our hearts operate and the way electrical impulses flow through our cardiovascular system.”

It’s important to understand the specific factors that contribute to arrhythmias to get a proper diagnosis and treatment, according to Gulati.

“While lifestyle choices can influence overall health, managing aging and congenital or genetic factors often requires a multifaceted and personal approach,” she said. 

“The more proactive you are about your heart health, the better. Regular check-ups and monitoring can help identify and manage these factors.”

‘What are arrhythmia treatments?’

Treatments for arrhythmia will differ depending on each individual’s symptoms and contributing factors, Gulati said. 

“It’s important for your doctors to have access to as much information as possible so they can make the most informed decisions about your care,” she said.

Early detection and intervention can significantly impact the long-term prognosis and reduce the risk of complications, such as stroke or heart failure, the doctor noted. 

“That’s why I stress the importance of providing real-time data to physicians about what you’re experiencing when you’re experiencing it,” she said. 

“This not only fosters a deeper understanding of your unique circumstances and needs, but it also allows your doctor to tailor treatments based on day-to-day insights.”
