What Causes Dizziness and Palpitations Together?

What It Means

When dizziness and palpitations occur at the same time, a shared underlying condition is usually responsible. 10 medical conditions are known to produce this symptom combination.

Key Factors

• →SVT with pre-syncope from transient hypoperfusion
• →Paroxysmal AF with rapid ventricular response and dizziness
• →Ventricular tachycardia with hemodynamic compromise
• →Orthostatic hypotension with reflex tachycardia
• →Hypoglycemia with sympathetically-driven palpitations and lightheadedness

Common Causes

• →SVT with pre-syncope from transient hypoperfusion
• →Paroxysmal AF with rapid ventricular response and dizziness
• →Ventricular tachycardia with hemodynamic compromise
• →Orthostatic hypotension with reflex tachycardia
• →Hypoglycemia with sympathetically-driven palpitations and lightheadedness

Related Conditions

• HypertensionHypertension (high blood pressure) is a condition where the force of blood against artery walls is consistently too high. Often called the 'silent killer', it usually has no symptoms but significantly increases the risk of heart attack, stroke, and kidney disease.
• Anxiety DisorderAnxiety disorders are among the most common mental health conditions, characterized by excessive fear, worry, or nervousness that interferes with daily activities. Types include generalized anxiety disorder (GAD), panic disorder, and social anxiety.
• Cardiac ArrhythmiaCardiac arrhythmia refers to irregular heart rhythms — the heart beats too fast, too slow, or with an irregular pattern. Some arrhythmias are harmless, while others (like atrial fibrillation) significantly increase the risk of stroke and heart failure.
• Aortic StenosisAortic stenosis is narrowing of the aortic valve opening, restricting blood flow from the heart. It causes exertional chest pain, syncope, and heart failure; valve replacement is required for severe symptomatic disease.
• Iron Deficiency AnemiaIron deficiency anemia is the most common nutritional deficiency worldwide, caused by inadequate dietary intake, blood loss, or malabsorption. It causes fatigue, pallor, shortness of breath, and pica; iron supplementation is the treatment.
• Atrial FibrillationAtrial fibrillation (AFib) is the most common cardiac arrhythmia, characterized by rapid and irregular atrial beating. It significantly increases stroke and heart failure risk.
• Panic DisorderPanic disorder is characterized by recurrent unexpected panic attacks with intense physical symptoms. It often leads to persistent worry about future attacks and behavioral avoidance.
• HypoglycemiaHypoglycemia is low blood sugar, typically below 70 mg/dL. Most common in people with diabetes, it causes rapid neurological and adrenaline-driven symptoms requiring prompt treatment.
