Heart Palpitations in Miami: When to See a Cardiologist or Electrophysiologist
A racing heart can feel alarming, especially when it happens suddenly, wakes you up at night, or makes you wonder if something is wrong with your heart.
For some people, palpitations feel like fluttering. For others, they feel like skipped beats, pounding, a fast heartbeat, or a sensation that the heart is beating out of rhythm. Sometimes they last a few seconds. Other times, they keep coming back and start to interfere with daily life.
Not every palpitation is dangerous, but recurring palpitations should not be ignored. In some cases, they may be related to stress, caffeine, dehydration, hormonal changes, or lack of sleep. In other cases, they may be a sign of an arrhythmia, which is a problem with the heart rhythm.
If you live in Miami, Hialeah, Coral Gables, or nearby areas and you are experiencing palpitations, understanding when to see a cardiologist or electrophysiologist can help you take the right next step.
What Are Heart Palpitations?
Heart palpitations are the sensation of being aware of your heartbeat. You may feel that your heart is beating too fast, too hard, irregularly, or differently than usual.
Patients often describe palpitations as:
- A fluttering feeling in the chest
- A racing heartbeat
- Skipped beats
- A pounding sensation
- A flip-flop feeling in the chest
- A heartbeat that feels irregular
- A fast pulse that appears suddenly
- A sensation that the heart is beating in the throat or neck
Palpitations may happen during exercise, after coffee, during stress, while resting, or even while trying to sleep. The pattern matters because it can help determine whether the symptom is likely benign or whether it needs a heart rhythm evaluation.
Common Causes of Palpitations
Palpitations can have many causes. Some are temporary and lifestyle-related, while others may involve the electrical system of the heart.
Common causes may include:
- Caffeine or energy drinks
- Nicotine
- Alcohol
- Stress or anxiety
- Lack of sleep
- Dehydration
- Fever or illness
- Anemia
- Thyroid imbalance
- Hormonal changes
- Certain medications or supplements
- High blood pressure
- Heart valve problems
- Arrhythmias such as atrial fibrillation, supraventricular tachycardia, or premature beats
This is why the context is important. A single episode after drinking too much caffeine may not mean the same thing as repeated episodes that happen at rest, come with dizziness, or appear on a smartwatch as an irregular rhythm notification.
When Palpitations May Be Related to an Arrhythmia
An arrhythmia is an abnormal heart rhythm. It can make the heart beat too fast, too slow, or irregularly. Some arrhythmias are mild. Others require closer evaluation, monitoring, or treatment.
One common arrhythmia is atrial fibrillation, also known as AFib. AFib can cause fluttering, palpitations, fatigue, shortness of breath, dizziness, or reduced exercise tolerance. Some people feel obvious symptoms, while others have silent or intermittent episodes.
AFib matters because, when untreated, it can increase the risk of stroke and other complications. That does not mean every palpitation is AFib, but it does mean persistent or recurring symptoms deserve attention.
Signs You Should Not Ignore
You should seek medical attention promptly if palpitations are new, frequent, worsening, or associated with other symptoms.
Symptoms that should be taken seriously include:
- Chest pain or pressure
- Shortness of breath
- Dizziness or lightheadedness
- Fainting or near-fainting
- Unusual fatigue
- A heartbeat that feels very fast or irregular
- Palpitations that happen during exercise
- Palpitations with a known heart condition
- A smartwatch or device alert suggesting irregular rhythm
- A family history of sudden cardiac death or rhythm problems
If palpitations occur with severe chest pain, trouble breathing, fainting, or symptoms of a heart attack, call 911 or seek emergency care immediately.
What If Your Apple Watch or Smartwatch Shows an Irregular Rhythm?
Many patients now notice heart rhythm changes because of wearable devices. Smartwatches can be helpful because they may detect patterns that happen outside the doctor’s office.
However, a smartwatch notification is not a final diagnosis. It is a signal that should be reviewed in the right clinical context. A cardiologist or electrophysiologist can determine whether additional testing is needed, such as an ECG, Holter monitor, event monitor, or other heart rhythm evaluation.
If your device repeatedly shows irregular rhythm, high heart rate at rest, or possible AFib, it is reasonable to schedule a medical evaluation rather than dismissing the alert or trying to interpret it alone.
Why an Electrophysiologist May Be Important
A cardiologist focuses on the heart and cardiovascular system. An electrophysiologist is a cardiologist with advanced training in the electrical system of the heart and heart rhythm disorders.
This distinction matters for patients with palpitations, irregular heartbeat, fainting episodes, AFib, supraventricular tachycardia, or unexplained rhythm symptoms.
An electrophysiologist can help evaluate:
- Whether symptoms are related to an arrhythmia
- What type of rhythm problem may be present
- Whether monitoring is needed
- Whether medication, lifestyle changes, or procedures may be appropriate
- Whether the patient needs long-term rhythm follow-up
For Global Cardiology Care, this is an important area of differentiation because Dr. Paloma Piña is trained in cardiology and electrophysiology, allowing patients to receive specialized rhythm evaluation in one place.
What Happens During a Palpitations Evaluation?
A heart rhythm evaluation usually begins with a detailed conversation about symptoms. The timing, duration, triggers, and associated symptoms can reveal important clues.
Your evaluation may include:
- Medical history and family history
- Review of medications, caffeine, alcohol, supplements, and lifestyle factors
- Blood pressure and cardiovascular exam
- Electrocardiogram, also called an ECG or EKG
- Ambulatory monitoring, such as a Holter monitor or event monitor
- Echocardiogram, when indicated
- Blood work to evaluate thyroid function, anemia, electrolytes, or other contributing factors
- Review of smartwatch rhythm strips or alerts, when available
The goal is not to assume the worst. The goal is to understand whether the palpitations are harmless, lifestyle-related, or connected to a heart rhythm condition that needs treatment.
Why Miami Patients Should Pay Attention
In Miami, palpitations can be influenced by heat, dehydration, stress, stimulant use, long workdays, intense exercise, and underlying medical conditions such as high blood pressure, diabetes, thyroid disease, or sleep apnea.
For many patients, especially those in Hialeah, Coral Gables, and surrounding communities, symptoms may be ignored until they become more frequent. But rhythm problems are often easier to evaluate when the patient can describe the pattern early and bring device alerts, pulse readings, or symptom notes to the appointment.
The Takeaway
Heart palpitations are common, but they should not be dismissed when they are recurring, intense, or associated with other symptoms.
If your heart feels like it is racing, fluttering, skipping beats, or beating irregularly, a cardiology and electrophysiology evaluation can help determine what is happening and what steps may be needed.
At Global Cardiology Care, Dr. Paloma Piña provides cardiovascular and heart rhythm care for patients in Miami and surrounding areas. If your heart is sending signals that something feels off, it may be time to listen and schedule an evaluation.
