Tachycardia
Synopsis
Tachycardia refers to a condition where the heart beats faster than normal—typically over 100 beats per minute in adults—while at rest. It can be harmless and temporary, such as during exercise or stress, or it may signal an underlying heart or systemic condition. Tachycardia is classified based on its origin in the heart (atrial or ventricular) and can be caused by electrical misfiring, systemic stress, or structural heart disease. Sustained or uncontrolled tachycardia can reduce the heart’s efficiency, leading to dizziness, fatigue, chest pain, or even cardiac arrest if untreated.
Types:
-
Sinus tachycardia: Normal response to stimuli (e.g., exercise, anxiety, fever)
-
Supraventricular tachycardia (SVT): Rapid signals originating above the ventricles
-
Ventricular tachycardia: Originates in the ventricles—can be life-threatening
-
Atrial fibrillation or flutter: Irregular atrial rhythms often causing a fast heart rate
-
Postural orthostatic tachycardia syndrome (POTS): Heart rate rises abnormally upon standing
Common Causes:
-
Physical exertion or emotional stress
-
Fever or infection
-
Dehydration or electrolyte imbalance
-
Anemia or blood loss
-
Stimulant use (e.g., caffeine, nicotine, certain medications)
-
Thyroid disorders (especially hyperthyroidism)
-
Heart disease, valve problems, or cardiomyopathy
Severity Causes:
-
Underlying cardiovascular disease
-
Poor vagal tone or autonomic dysfunction
-
Inadequate oxygenation or chronic pulmonary disease
-
Electrolyte disturbances (e.g., low magnesium or potassium)
-
Medication interactions or withdrawal
-
Chronic dehydration or adrenal overactivation
When to See a Doctor:
-
Resting heart rate consistently above 100 BPM
-
Palpitations, lightheadedness, or chest tightness
-
Fainting, shortness of breath, or fatigue during episodes
-
History of heart disease or arrhythmias
-
If symptoms begin suddenly or worsen rapidly
Natural Remedies
Magnesium: Helps regulate heart rhythm and prevent electrical instability. Especially beneficial in cases of stress-related or electrolyte-based tachycardia.
Omega-3 fatty acids: Support cardiovascular health and reduce inflammation, potentially lowering heart rate over time.
Ashwagandha: Adaptogen that supports adrenal function and reduces stress-induced heart rate increases.
Coenzyme Q10 (not in your list, but worth noting for future): Supports mitochondrial energy in heart cells and may help regulate rhythm.
L-theanine: Naturally calming amino acid that promotes parasympathetic (rest-and-digest) activity, reducing elevated heart rate due to anxiety or overstimulation.
Hydration and electrolytes: Maintaining fluid and electrolyte balance (especially sodium, potassium, and magnesium) is critical for electrical stability in the heart.
Breathing exercises and vagal stimulation: Slow deep breathing, humming, or cold water face immersion activate the vagus nerve, slowing heart rate naturally.
Avoid triggers: Limit caffeine, nicotine, alcohol, and stimulant medications known to elevate heart rate.
